Impact Socket 21mm 1/2in Drive CR-MO

A 21mm impact socket with a 1/2in drive, made for work where a standard socket may not stand up as well. Built from Cr-Mo and sized for a common fastening job, it suits both powered and manual use around the garage or workshop.

Used for vehicle maintenance, machinery repair and general workshop jobs, this socket is a practical choice for mechanics, tyre fitters and DIY users who need a dependable everyday size. It can be used with an impact wrench for quicker fastening and removal, or with a ratchet or breaker bar when working by hand. That makes it useful for servicing, repair work and routine maintenance where one socket may need to move between different tools.

This 21mm socket covers a common fastening requirement, while the 1/2in drive fitting suits widely used impact and hand tools. Cr-Mo construction makes it suitable for the repeated demands that come with impact use, and the 38mm height keeps the socket compact and easier to handle where access is a bit tighter. It can also be secured to an impact wrench with a pin and O-ring, which is useful when you want the socket properly fixed in place during use. For regular garage work, it is a straightforward option that helps keep a commonly used size close to hand without overcomplicating the job.
