Hex Screwdrivers (Allen Wrenches)

What they are: Hex screwdrivers (also commonly known as Allen wrenches or hex keys) have a hexagonal (six-sided) tip that fits into a hexagonal recess in the screw head. They come in various sizes, typically measured in millimeters (for metric) or inches (for SAE).

Common forms:

• L-shaped keys: The most common form, often found in sets, providing good leverage.
• T-handle hex drivers: Offer a more ergonomic grip and better torque for certain applications.
• Hex bits: For use with screwdriver handles, bit drivers, or power drills.

What they are used for: Hex fasteners are known for their ability to withstand higher torque without stripping compared to Phillips or slotted screws. You’ll find them widely used in:

• Furniture assembly: Very common for assembling flat-pack furniture (e.g., IKEA).
• Bicycle maintenance: Adjusting brakes, handlebars, and other bike components.
• Automotive repairs: Many vehicle components use hex bolts.
• Machinery and equipment: Used in various industrial and consumer electronics.
• DIY projects: Any application requiring secure, high-torque fastening.

Torx Screwdrivers (Star Screwdrivers)

What they are: Torx screwdrivers (also known as star screwdrivers or 6-point star drivers) have a distinctive 6-point, star-shaped tip that mates with a corresponding recess in the screw head. Torx screws were developed to improve upon Phillips head screws by reducing “cam-out” (where the driver slips out of the screw head) and allowing for higher torque application without damaging the fastener or tool.

Common forms:

• Individual screwdrivers: With a fixed Torx tip and handle.
• Torx bits: For use with screwdriver handles, bit drivers, or power drills.
• Torx key sets: Similar to L-shaped hex keys, but with Torx ends.
• Security Torx (Tamper-Resistant Torx): These have a small pin in the center of the star recess, requiring a Torx bit with a corresponding hole. This design is used to deter tampering.
