Impact Socket 21mm 1in Drive CR-MO 58mm

A 21mm impact socket with a 1in drive, made for heavier fastening work where a standard socket may not be suitable. Built from CR-MO and sized at 58mm overall height, it is intended for use with both manual tools and impact wrenches.

Used in garages, workshops and plant maintenance, this socket suits jobs involving larger fixings that need proper torque and a secure fit. It is a practical option for mechanics, trade users and anyone carrying out vehicle maintenance, repair work or servicing with a 1in drive setup. When a job moves between hand tools and an impact wrench, using one socket for both can make day-to-day work more straightforward.

The 21mm size covers a specific common fastening size in heavier-duty applications, while the CR-MO construction is suited to impact use. A 1in drive fitting makes it suitable for larger tooling, and the 58mm height gives a clear idea of the socket's overall working size. It can also be fixed to an impact wrench using a pin and O-ring, which is useful where secure retention matters during repeated use. For regular workshop and maintenance tasks, that helps keep the right socket ready for the job without swapping between different types.
