Bit Holder 5/16in 9 x 12mm Push Fit Locking Pin

A 5/16in bit holder made for use with a 9 x 12mm torque wrench head or interchangeable head setup. The push fit design makes it a quick change bit holder, while the locking pin helps keep it secure in use.

Used where 5/16in bits are already part of the job, this holder suits servicing, fitting and regular workshop tasks where a torque wrench setup needs the correct attachment. It is a practical option for replacing a worn holder, keeping a spare in the toolbox, or matching an existing interchangeable head system for garage work, vehicle maintenance and general repair jobs.

The 9 x 12mm drive size makes it suitable for compatible setups, and the chrome plated finish helps keep it practical for repeated workshop use. Bit changes stay straightforward thanks to the push fit design, which is useful when swapping between different 5/16in bits during the same job. The locking pin adds extra security under load, helping give more confidence when tightening with a torque wrench. Supplied fitment information confirms it fits CT7145, which is useful if you are replacing the original holder or keeping the right attachment close to hand.
