Screwdrivers & Hex Keys

Learn more about screwdrivers and hex keys

Screwdrivers and hex keys are used across fixing, assembly and maintenance work. The key is to pick the right drive type first, then match the size and fit to the fixing in front of you.

Typical uses

• Use a hex key or hex driver for recessed hex (socket) bolts, common on furniture, angels and brackets, and mechanical fixings.

• Use a screwdriver or bit driver for slotted, Phillips, Pozidriv and Torx screw heads.

• Reach for precision screwdrivers on small fixings and delicate assemblies where control matters.

• Choose torx screwdrivers for security and machine fixings that need a tighter, slip resistant fit.

• Keep a bit set on hand for mixed jobs where the fastener profile changes as you go.

How to choose the right screwdriver or hex key

• Identify the head type first: slotted, Phillips, Pozidriv, Torx or hex. Using a Phillips on a Pozidriv, or the wrong size on either, is the quickest route to a stripped head.

• Check sizing carefully, and make sure the tool suits the fixings you work with.

• Look at tip accuracy and shaft length. A precise tip seats fully in the recess, and the right length gives you access in tight spots without losing control.

• Consider magnetic screwdrivers for holding screws on the tip in awkward positions, and reversible ratcheting screwdrivers for faster, lower effort driving on repetitive work.

• Check handle comfort and grip. A grip you can hold under load reduces slip and fatigue across a long day.

• For mixed fastening work, a set of screwdrivers, hex bit set or screwdriver bits can give you the flexibility to switch between head types.

• Avoid rounding or stripping fasteners by using the correct size, seating the tool fully and applying steady, in line pressure rather than forcing at an angle.

Before you order

• Confirm the size range covers the fixings you actually work with, in the right measurement standard.

• Decide whether a single tool or a set gives better coverage for your typical jobs.

• Check the tool suits the application, from precision work to bolted assemblies under torque.

• Think about grip, balance and access in tight spaces, and the level of control the job needs.

• Check stock availability and fulfilment options before you add items to your basket.
