20-piece hex bit set metric SAE

This set contains twenty S2 steel hex bits covering both metric and SAE sizes. The bits measure 2.3 inches long and feature magnetic tips for secure fastener engagement. A storage box keeps the pieces organised and protected during transport.

Mechanics needing metric and imperial sizes

The kit suits technicians who regularly switch between 1.5 to 8 mm and 5/64 to 5/16 inch fasteners. It is not intended for users who only need one measurement system or who require impact-rated bits for high-torque drivers.

S2 alloy steel construction

Each bit is forged from S2 alloy steel with hardened and tempered treatment for wear resistance. The 1/4 inch hex shank fits standard drill chucks and screwdriver handles. This material choice determines the set's durability under repeated use.

Questions about this item

Will the 1/4 inch hex shank on these bits fit the older cordless drill I already own?

Yes, the 1/4 inch hex handle is designed for standard drill chucks and screwdriver bits, so it will work with your existing cordless drill.

How can I confirm the magnetic tips are holding screws securely before I start a job?

Place a screw on the bit tip; the magnetic tip should hold it firmly in any orientation without the screw falling off.

Does the set include both metric and SAE sizes and come with the storage box shown?

The set contains 10 metric bits from 1.5 mm to 8 mm and 10 SAE bits from 5/64 inch to 5/16 inch, all in the included storage box.
