Impact Socket 40mm 3/4in Drive CR-MO

A 40mm impact socket with a 3/4in drive, built for heavier fastening work where a standard socket may not cope with the load. The CR-MO construction makes it suitable for use with impact wrenches as well as manual tools, giving you a practical option for tougher jobs on larger fixings.

Used across garages, plant maintenance, agricultural work and general mechanical repair, this socket suits anyone dealing with stubborn nuts and bolts. It is useful for vehicle maintenance, workshop servicing and heavier DIY repairs where a strong drive tool is needed. Keeping this size to hand can save time when larger fasteners come up, whether you are working in trade use or regular repair work.

The 40mm size is intended for larger fixings, while the 58mm overall height gives the socket a compact, solid feel in use without being overly bulky. Its 3/4in drive fitment suits larger drive tools commonly used for higher torque applications. It can also be secured onto an impact wrench with a pin and O-ring, which helps keep the socket properly seated during demanding work. For repeated workshop use, the impact-rated CR-MO build makes it a sensible choice when ordinary sockets are not the right fit for the job.
