Wera 8740 B HF Zyklop 3/8 inch aandrijving Hex-Plus bit-dop, 3/16 inch met vasthoudfunctie 05003085001

Mechanics and technicians working on engines, machinery, or assembly lines need a bit socket that grips screws securely and prevents them from falling. The Wera 8740 B HF Zyklop bit socket is built for that: a 3/8" square drive socket with a 3/16" Hex-Plus profile and an integrated holding function. The Hex-Plus geometry increases the contact surface in the screw head, reducing notching and protecting the screw profile. The holding function holds screws firmly in place, making overhead or one-handed work easier. Made from chrome vanadium steel with a matt chrome-plated finish, this bit socket is durable and corrosion-resistant. It is suitable for manual and non-impact machine operation, conforming to DIN 3120 and ISO 1174 drive standards.
