ProFix 9-Piece Ball-End Hex Key Set, 1.5–10 mm

What it is for

Hex keys are the tools that round a socket head when they are made of the wrong steel, and the damage is done to the fastener, not the key. These are cut from CR-V steel and hardened through, so the short arm twists before the tip deforms — a failure you can see coming.

The folding holder keeps the sizes together and makes the key a lever, which is the point: for a recessed cap screw you often need more leverage than a bare key gives, and the holder is the difference between loosening it and rounding it.

Specification detail

9 keys covering 1.5–10 mm, cut from CR-V steel with a black oxide finish finish and hardened through rather than surface-hardened. Supplied in a folding holder that indexes each size; short arm and long arm at the standard length ratio for a recessed cap screw.

• Hardened through — the key twists before the tip damages the fastener
• Folding holder doubles as a lever for recessed cap screws
• Sizes marked on the holder, so a missing key is spotted at a glance
• CR-V steel with a black oxide finish finish, resistant to workshop humidity
