Proline screwdriver bit set 7 pcs, 10 mm shank, H4–H12

Proline screwdriver bit set 7 pcs, 10 mm shank, H4–H12 includes seven short (30 mm) hardened hex bits with sizes H4, H5, H6, H8, H10 and H12 plus a 1/2" adapter. The bits have a 10 mm shank and are intended for use with compatible bit holders, ratchets and power tools for assembly, maintenance and repair tasks in workshop, service or home environments.

Advantages

The set offers a compact selection of commonly used hex sizes in a short 30 mm length for work in confined spaces. Hardened construction increases durability and wear resistance, while the included 1/2" adapter allows use with standard 1/2" drives and ratchets. A 10 mm shank ensures secure fitting in compatible bit holders and power tool chucks.

Suitable for

• Assembly and disassembly of hex fasteners

How to use

Select the hex bit matching the fastener size, insert the 10 mm shank into a compatible bit holder, ratchet or power tool chuck, and secure it before applying torque. Use the 1/2" adapter when connecting the bit directly to a 1/2" drive or ratchet. Apply steady, controlled force to avoid rounding fastener heads and inspect bits periodically for wear.

Usage recommendations

For best results, use the short 30 mm bits in tight spaces and switch to longer bits if deeper reach is required. Replace any worn or damaged bits to maintain secure fit and prevent damage to fasteners.
