When you need a reliable screwdriver bit that works with your 7mm hex screws, you can count on this one from GEDORE. It's made from vanadium steel for strength and hardness, with a manganese phosphate coating that ensures resistance to corrosion. A ball retaining groove helps the bit to hold the hex pin securely to prevent slips. Thanks to its 1/2-inch drive size, it's broadly compatible with standard tools.

• Size stamped clearly on the body for hassle-free identification and organisation
• Overall length of 60mm gives you the reach to access recessed nuts

• Electrical engineering
• DIY projects
• Automotive manufacturing

It helps you to keep a firm hold on your socket drive when inserting and securing it into your socket wrench, even with damp or greasy hands.
