Wera 784C/2 1/2" Square Drive to 5/16" Hex Screwdriver Bit Holder

The Wera 784C/2 is a 1/2" square drive to 5/16" hex screwdriver bit holder, designed to allow the use of large-format screwdriver bits directly with a 1/2" square drive ratchet or torque wrench.

This adaptor bridges the gap between your 1/2" square drive tools and bits conforming to DIN ISO 1173-C 8 with a 5/16" hexagonal drive — part of Wera's connecting series 2. It's a practical solution for contractors and engineers who need to drive large fixings with the added torque and control of a 1/2" drive tool.

The quick-release chuck allows for rapid bit changes on the job, reducing downtime when switching between fastener types. The ball stop groove ensures a secure, positive connection between adaptor and socket drive, helping to prevent slippage during use.

• 1/2" square drive to 5/16" hex adaptor for use with large-format screwdriver bits
