When tackling construction, woodworking, automotive repairs, or DIY projects, using the right screwdriver bit can make all the difference. Choosing the correct screw bit type prevents stripping, increases efficiency, and ensures a secure fit.
This guide covers the most common screwdriver bits, their uses, and which high-quality bit sets to consider for your toolbox.
1. Phillips (PH) – The Most Common Screw Bit
✔ Most widely used screw bit
✔ Cross-shaped tip for better grip
✔ Used in furniture, appliances, electronics, and construction
Why Use a Phillips Bit?
Phillips screwdriver bits self-center and provide better torque, reducing slippage. However, excessive force can cause cam-out, where the bit jumps out of the screw head.

✔ Less likely to strip but prone to slipping
Why Use a Slotted Bit?

3. Torx (Star) – Best for High Torque Applications
✔ Six-point star-shaped bit for a secure grip
✔ Used in automotive, machinery, and electronics

Why Use a Torx Bit?
Torx bits increase torque without stripping screws, making them ideal for power tools, automotive repairs, and industrial machinery.
4. Hex (Allen) – Essential for Furniture & Machinery

✔ Prevents stripping and allows high torque application
✔ Common in IKEA furniture, automotive, and power tools
Why Use a Hex Bit?
Hex bits are often used with Allen wrenches, but power tool bits increase speed and efficiency when working with fasteners, bicycles, and furniture assembly.
5. Square (Robertson) – Best for Grip & No Slippage
✔ Square-shaped tip for high grip
✔ Popular in carpentry, decking, and heavy-duty applications
✔ Less prone to cam-out than Phillips bits
