The Anatomy Of A Screwdriver

Before diving into the types, it helps to know the main parts of a screwdriver:

• Handle: Usually made from plastic, rubber, or wood for grip.
• Shaft (or shank): The long, metal part connecting the handle to the tip.
• Tip (or blade): The shaped end that fits into the screw.

Some screwdrivers also have extra features, like a magnetic tip or an insulated handle for electrical work.

The Most Common Types Of Screwdriver

There are several main categories, each with its own unique shape and use. Here are the most widely used types, along with their characteristics and applications.

1. Flathead (slotted) Screwdriver

The flathead is the original screwdriver design. Its tip is a simple, flat blade that fits into screws with a straight, single slot. Flathead screwdrivers are used everywhere—from woodworking to electrical work. They are especially good for older screws and simple DIY tasks.

However, they can slip out of the screw slot easily if not held straight. This slipping is called “cam-out,” and it can damage both the screw and your work surface. Flathead screws are also less common in modern manufacturing, but you’ll still find them in furniture, light switches, and older electronics.

2. Phillips Screwdriver

The Phillips screwdriver is probably the most recognized. Its tip has a cross shape, designed to fit screws with a “+” shaped slot. This design helps the screwdriver stay centered and gives you more turning power. Phillips screwdrivers are used in everything from toys and kitchen appliances to computers and vehicles.

A common mistake is using the wrong size Phillips screwdriver, which can strip the screw head. Always match the size of the screwdriver tip to the screw for the best grip.

3. Pozidriv Screwdriver

The Pozidriv looks like a Phillips, but has extra lines between the main cross slots. This gives more grip and reduces the chance of slipping. Pozidriv screws and screwdrivers are popular in Europe, especially in furniture and electrical work. Using a Phillips driver on a Pozidriv screw (or vice versa) can damage both the tool and the screw.

One non-obvious insight: Pozidriv screwdrivers are often marked with a “PZ” and a number. This number should match the Pozidriv screw for a perfect fit.

4. Torx (star) Screwdriver

The Torx screwdriver has a star-shaped tip with six rounded points. It’s common in cars, electronics, and high-end appliances. Torx screws allow for higher torque without slipping, making them popular in professional repair and assembly lines.

Torx sizes are usually marked as T10, T15, T20, etc. Using the wrong size can damage the screw or the driver. Some security versions have a pin in the center, requiring a special “security Torx” driver.

5. Hex (allen) Screwdriver

Hex screwdrivers fit screws with a six-sided, hexagonal hole. Most people know these as Allen keys or Allen wrenches, but hex screwdrivers with a handle are easier to use for repeated tasks or hard-to-reach places.

You’ll see hex screws in furniture kits, bicycles, and machinery. They are less likely to strip than Phillips or flathead screws. One expert tip: Use a ball-end hex driver when you need to reach screws at an angle.

6. Robertson (square) Screwdriver

The Robertson screwdriver has a square-shaped tip. It’s very popular in Canada and is used in woodworking, construction, and automotive work. The square tip gives a strong grip and prevents slipping, even when you apply a lot of force.

Robertson screws are color-coded by size, making it easier to pick the right tool. One reason these screws aren’t more common worldwide is because of old patent restrictions, but today they’re found in many industries.

7. Security Screwdrivers

Many screws are designed to prevent tampering or theft. These need special security screwdrivers, which come in many types:

• Torx Security (with a pin in the center)
• Spanner (two holes instead of a slot)
• Tri-Wing (three slots, used in electronics)
• Snake Eye (two dots, often for bathroom fixtures)

These screwdrivers are essential for repair shops or anyone working with public equipment. Using the wrong tool can strip the screw and make removal impossible.

8. Clutch Screwdriver

The clutch screwdriver has a tip that looks like a bow tie or butterfly. It’s used mostly in older cars, trucks, and RVs, especially from the 1940s to 1970s. Clutch screws are rare today but still found in some heavy-duty machinery.

9. Frearson (reed And Prince) Screwdriver

The Frearson tip looks similar to Phillips, but the cross is sharper and comes to a point. This allows one size of Frearson driver to fit many screw sizes. It’s popular in marine and aviation industries, where versatility and reliability are important.

10. Tri-point Screwdriver

The tri-point has a tip shaped like a “Y” with three points. You’ll find these screws in Apple devices, Nintendo consoles, and some smartphones. They’re used to prevent tampering and require a matching tri-point driver for service.

11. Nut Driver

A nut driver looks like a screwdriver but has a socket at the end to fit over hexagonal nuts and bolts. It’s commonly used in electronics, HVAC, and appliance repair. Nut drivers come in different sizes to match various nuts.

12. Offset Screwdriver

An offset screwdriver has a handle set at a right angle to the shaft, allowing you to turn screws in tight spaces where a regular screwdriver won’t fit. They come in both flat and Phillips tips. This tool is a lifesaver for hard-to-reach spots behind sinks or inside machines.

13. Precision Screwdriver

Precision screwdrivers are smaller versions of regular screwdrivers, made for delicate screws in watches, eyeglasses, phones, and laptops. They usually come in sets with several tip types and sizes. These tools have thin, fine shafts for working on tiny components without damage.

14. Insulated Screwdriver

An insulated screwdriver is designed for electrical work. Its handle and shaft are coated to protect you from electric shock, usually rated for up to 1000 volts. Electricians use these when working with wiring or electrical panels. Never use a regular screwdriver for electrical work, even if you think the power is off.

15. Ratcheting Screwdriver

A ratcheting screwdriver has a mechanism that lets you turn the screw without lifting and repositioning your hand. You can switch directions for tightening or loosening. Many ratcheting screwdrivers have interchangeable bits for different screw types. They save time and reduce hand fatigue during long tasks.

16. Magnetic Screwdriver

A magnetic screwdriver has a magnetized tip to hold onto screws. This is especially helpful when working in tight spots or overhead, where dropping a screw would be a problem. Magnetic tips are available in many screwdriver types, not just one.

17. Interchangeable (multi-bit) Screwdriver

A multi-bit screwdriver lets you swap out different tips or bits, making it very versatile. You can carry one handle and several bits instead of a whole set of screwdrivers. These are popular for home repairs and electronics work.

18. Stubby Screwdriver

A stubby screwdriver is short and compact, designed for working in cramped spaces. It comes in flat, Phillips, and other tip styles. The short handle gives less torque but more control in tight areas.

19. Jeweler’s Screwdriver

Jeweler’s screwdrivers are ultra-small, made for the tiniest screws in watches, glasses, and electronics. They’re usually sold in sets with both flat and Phillips tips. The handle often has a rotating cap for precise, one-handed control.

20. Electric (powered) Screwdriver

An electric screwdriver is battery-powered, turning screws much faster than by hand. These are great for assembling furniture, installing cabinets, or building decks. Some models have adjustable torque settings, LED lights, or even smart features.

Electric screwdrivers save time and energy, but you still need to match the right bit to the screw.

Specialized And Less Common Screwdriver Types

While the types above cover most needs, there are also some unusual or specialized screwdriver types worth knowing about.

Triangular Screwdriver

Triangular screwdrivers fit screws with a triangle-shaped slot. These are often found in toys, appliances, and products where manufacturers want to prevent tampering.

Spanner (snake Eye) Screwdriver

The spanner screwdriver has a tip with two round pins. It fits into matching holes in the screw head, commonly used in public bathroom fixtures and elevators for security reasons.

Japanese Industrial Standard (jis) Screwdriver

The JIS screwdriver is designed for Japanese-made screws, especially in electronics and vehicles. JIS screws look like Phillips, but using a Phillips driver can strip them. A JIS screwdriver fits perfectly and prevents damage.

Offset Phillips Screwdriver

This is a variation of the offset screwdriver but with a Phillips tip. It’s useful for tight spaces where you need a cross-shaped driver.

Torque Screwdriver

A torque screwdriver lets you set a specific torque value, ensuring screws are tightened to the correct level. This is important in electronics, automotive, and aerospace industries where over-tightening can cause damage.

Watchmaker’s Screwdriver

These are very fine precision screwdrivers made for assembling and repairing watches. They offer extra control for the tiniest screws.

Cabinet Screwdriver

A cabinet screwdriver has a long, thin shaft and a narrow tip, designed to fit into deep holes or tight spaces, such as inside cabinets or behind panels.

Computer (electronics) Screwdriver Set

These sets include a mix of small Phillips, flat, Torx, and sometimes pentalobe drivers for opening computers, phones, and tablets.
