What is Screwdriver?

 

A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional "grip". Their handles are typically wood, metal, or plastic and usually hexagonal, square, or oval in cross-section to improve grip and prevent the tool from rolling when set down. Some manual screwdrivers have interchangeable tips that fit into a socket on the end of the shaft and are held in mechanically or magnetically.

Interchangeable Head (Multi-Bit)
Like power screwdrivers, these have interchangeable heads but are manually operated. The main benefits are flexibility and less clutter in your toolbox. Some models offer accessories to organize and store the bits so you don’t lose any pieces.

 

Flat-Head
The flat head is one of the most common screwdrivers. Slotted screws come in a number of different shapes and sizes, often requiring differently sized heads despite the same general shape. If your screwdriver is too small, it will require more torque and effort to turn the screw just a little; too large and it won’t fit in the screw.

 

Phillips
A Phillips screwdriver has a head with pointed edges in the shape of a cross, which fits neatly into the cross slots of a Phillips screw. Phillips screwdrivers are available in five different sizes, from zero to four. If you don’t use the right size, you can easily strip a Phillips screw, making it difficult to remove.

 

Square
Also known as a Robertson tip, the square tipped head was designed to prevent stripping or damaging the screw. Square screws are commonly used in Canada. There are five different sizes of square screwdrivers available.

 

Hex Key/Screwdriver
The hex key or hex wrench, is an L-shaped tool with a hexagonal cross section. These are commonly included with DIY furniture pieces. Hex Keys are commonly sold in sets.
Precision hex screwdrivers are great for turning small screws on sensitive electronic components. Drivers have handles with a rotating cap that allows the user to hold the shaft of the screwdriver steady while only rotating the cap at the back.

 

Torx Key/Screwdriver
Torx keys are similar to hex keys and have the same L-shape, except this tool has a six-point, star-shaped cross section. Torx screwdrivers provide a secure grip on the fastener head.

 

Triangle (TA)
The triangle or TA screwdriver has a triangular head with straight sides. Triangle screws are used for security reasons because they're difficult to remove without a TA screwdriver.

 

Tri Wing
Tri-wing screwdrivers are only compatible with a fastener head that has three slotted "wings" and a small triangular hole in the center. Also known as triangular slotted, the slots are offset and do not intersect in the center of the fastener.

 

Pozidriv
These screwdrivers are a variant of the Phillips and can be identified by four additional notches in the screw head. Pozidriv was designed to provide increased torque over the Phillips.

 

Components of Screwdriver

 

 

The three main parts that constitute a screwdriver are as follows:
●Handle
●Shaft or shank
●Drive tip or bit
All three parts are made in a production process using machines to form the correct shape of material using an extruder and heat-treating it to achieve the desired tensile strength.

 

Screwdriver Handle
Screwdriver handles are used for gripping and are generally shaped to prevent rolling on flat surfaces. They can also be ergonomically-designed to improve comfort when gripping. The materials used in the manufacturing process have changed over time and there is now also more variety for tools intended for use in specific applications. Most commonly, the handles are ergonomic and made of a composite of hard plastic such as cellulose acetate and rubber. They can also be covered in a non-slip, soft material like thermoplastic rubber to improve grip.

Shaft or Shank
The shaft or shank is commonly made of strong steel to ensure that bending or twisting deformation does not occur when applying force. The shaft will be rounded or hexagonal to allow a spanner or wrench to be used to apply increased torque. The shaft is generally different colouration and material to the drive tip which can be interchangeable.

Drive Tip or Bit
The drive tip can be an integrated part of the shank if it is not detachable. Alternatively, it can be an interchangeable part known as a driver - similar to drill bits. These are designed for use with multi-bit tools. The tip may also be known as the screwdriver head.

 

 
Solutions to Manage Heads of Screwdriver

 

Wrong Insert Bit or Damaged Bit
If you’re trying to make do with the wrong size bit, you’ll almost certainly strip the screw head because a bit that’s undersized or oversized relative to the fastener will not turn it properly. Likewise, a damaged bit that is chipped or severely worn will rotate inside the recess in the screwhead, stripping it.
Solution: Buy a high-quality set of bits to ensure that you are more likely to have the size you need, and rotate out bits as they are worn or damaged. Also, having a large selection to choose from also distributes the wear and tear over many bits and makes it more likely you can quickly swap out a bit that’s worn down

 

Overtightening
A lot of people think that that it’s better to make a screw a little too tight than leave it loose. In other cases, fatigue or a poor grip can cause someone to inadvertently overtighten. Regardless, of the cause, overtightening is a sure way to strip a fastener. A lot of this comes down to better technique and implementing the solution mentioned above (use the right bit and replace damaged or worn bits).

Solutions: Tighten the screw firmly but when you feel that the screwdriver bit or the head wants to cam out (that is, rotate out of the screw slot) stop tightening. You can also tighten the screw, stop, adjust your hand position on the screwdriver, then apply a little more downward force as you torque the screw carefully the rest of the way home.

 

Can’t Reach
When people struggle to reach a screw, they tend to mangle the screw head once they manage to get in contact with it.
Solution: Consider buying a small selection of screwdrivers with longer shafts, or a single tool with an adjustable shaft, enabling the user to change the screwdriver’s length from 4 inches to 8 inches.

 

Difficulty Handling the Screwdriver
Even if you can reach a screw, have a properly sized screwdriver or a bit that accurately matches the screw, none of this will do you any good at all if you can’t comfortably, powerfully, and consistently apply torque. If your hand slips or you have trouble applying torque, you’ll almost certainly strip that screw head.
Solution: As basic as it sounds, reliably turning a screwdriver starts with a good grip. Look for screwdrivers with large-diameter handles, tri-lobe handles and cushioned handles with features such as soft rubber, non-slip surfaces inset into the handle. All of this improves your grip and in so doing provides for more consistent torque.

Frequently Asked Questions of Screwdriver
 

Q: What is screwdriver tool used for?

A: Screwdrivers are a type of hand tool used for the insertion and removal of screws. They are available in a multitude of variations to correspond to the correct screw drive. The drive or head of a screw has a shaped cavity and protrusion that fits the screwdriver tip.

Q: How does a screw work?

A: Screws change a gentle turning force into a strong forwards force. They do this with a spiral pattern called a “thread”, which runs round and round the screw from the wide top to the narrow end. Each time the screw is turned, the thread pulls it a short distance along.

Q: What is the common type of screwdriver?

A: The most commonly used screwdriver types are flathead screwdrivers (also called slotted screwdrivers) and Phillips screwdrivers (also called crosshead screwdrivers).

Q: How do I choose a screwdriver?

A: (1)Slot: Choose the correct screwdriver slot configuration and slot size that is compatible with the screw.
(2)Grip: A padded grip helps reduce hand fatigue.
(3)Shank: The shank extends from the handle to the head of the screwdriver and it comes in a variety of lengths.

Q: Is screwdriver a driving tool?

A: A screwdriver is a tool used to turn (or "drive") screws into something. It has an axial shaft with a tip of a certain shape that fits into the head of a screw. On the other end of the screwdriver is a cylindrical handle to be held by a person's hand.

Q: What is the L shaped screwdriver called?

A: The hex key or hex wrench, is an L-shaped tool with a hexagonal cross section. These are commonly included with DIY furniture pieces. Hex Keys are commonly sold in sets.

Q: What can I use instead of a tiny screwdriver?

A: The first thing you could try is a kitchen knife. Choose one that has a rounded tip like a butter knife or a small knife that you would use for a cheese board. Take the blade tip and angle the handle down toward the ground to give yourself some leverage. If you don't have a butter knife on hand, try a dime.

Q: Is a cordless screwdriver better than a drill?

A: Cordless screwdrivers have more maneuverability when compared to drills due to their lightweight structure, making them much easier to handle and allowing them into tight spaces where larger ones may not fit. Cordless screwdrivers have much shorter battery life when compared to drills.

Q: How do you screw a screw without a drill?

A: Place the tip of the screwdriver on the slot on the screw head first. Then, position the tip of the screw onto the pilot hole. Hold the screwdriver firmly, press down and turn it, driving the screw is driven into the wood.

Q: How to maintain the screwdriver?

A: If the screwdriver is damaged or blunt, it should be sharpened at any time. When grinding with a grinding wheel, it should be cooled with water. If the screwdriver cannot be repaired, if it is severely damaged, deformed, or the handle is cracked or damaged, it should be discarded in time.

Q: How do I know if my screwdriver is too small?

A: To determine the right size screwdriver, place the screwdriver head into the head of the screw. If the screwdriver head extends out of the screw head, the screwdriver is too large. If the screwdriver head does not reach the edges of the screw, the screwdriver is too small.

Q: What is the common problem of screwdriver?

A: A common problem involves slippage of the tip within the screw head, or movement of the item being worked on, with the possibility of a hand injury to the worker. Eye injuries from flying particles or electrical shocks while using a screwdriver are other possibilities.

Q: What are screwdrivers made of?

A: The screwdriver's tip is usually made of hard metals such as carbon steel, alloy steels, or ceramics. However, it can also be made of more rigid plastics such as nylon. The screwdriver handle material is usually made of wood, metal, plastic, or composite materials.

Q: Is a thicker or longer screw better?

A: If the piece will be subject to lateral pressure (pushing down or against), it is advisable to use a thicker screw. If the piece is subject to withdrawal pressure (pulling apart), then you will want to make sure that the screw is long enough to withstand those forces.

Q: Should I drill a hole before screw?

A: Pilot holes also reduce the chance of cracking your screw or stripping the screw head. A pilot hole can also make sure your screw is driven in the right direction and leave a smoother, more professional look. If you are going use a fastener in a soft material like a pine board, then pre-drilling may not be necessary.

Q: How do I know which screwdriver I need?

A: A flared tip screwdriver is sufficient for most work, but you should select a parallel tip that's the same width of the screw slot if you need to drive the screw below the surface of the wood without causing any damage. In fact, it's always important to select a tip that matches the width of the screw slot.

Q: What if my screwdriver is too big?

A: If it's too small, the screwdriver bit will move around, which can damage the inner walls of the screw's head recess. If it's too big, the screwdriver bit may only sit partially inside of the head recess, which can also cause damage to it. The bottom line is that you need to use a screwdriver bit in the right size.

Q: Can I wash a screwdriver?

A: Start by filling the bucket with hot water and a small amount of commercial cleaner. Soak your tools in the bucket for 30 seconds to a minute. With your wire brush, scrub the tools to remove dirt and grime. Rinse and repeat until all dirt has been cleared from the tool.

Q: What should I avoid doing using a screwdriver?

A: Do not use a screwdriver for prying, punching, chiseling, scoring, scraping or stirring paint. Do not use pliers on the handle of a screwdriver for extra turning power. A wrench should only be used on the square screwdriver shank designed for that purpose. Do not expose a screwdriver blade to excessive heat.

Q: Why do screwdrivers smell?

A: And this, ladies and gentlemen, is what screwdrivers and rotting butter have in common: butyric acid. While CAB is a hearty synthetic plastic and particularly handy for use in toolmaking, it can degrade with exposure to heat and moisture. This degradation releases butyric acid and that foul, vomit-like odor.
