Deep Impact Socket 21mm 1in Drive 6 Point CR-MO

A 21mm deep impact socket for 1in drive equipment, used for heavier fastening work where strength, reach and secure fitment matter. Made from CR-MO with a 6-point profile, it suits both impact wrench use and manual bar work on larger fixings.

Used across commercial vehicle maintenance, agricultural machinery repair, plant work and heavier workshop jobs, this CR-MO socket is suited to tasks where standard depth sockets may not clear longer studs or recessed nuts. It is a practical option for mechanics, fitters and anyone already working with 1in drive tools who needs a 21mm deep socket for regular fastening and removal work in tougher conditions.

The deep pattern gives extra access where space around the fixing is limited, with a 90mm overall height helping the socket reach further over protruding threads and awkward fasteners. CR-MO construction makes it suitable for impact use, while the 6-point design gives firm contact on the fastener faces. The pin and O-ring retention setup allows the socket to be secured onto an impact wrench, which is useful when tools are in frequent use and helps keep the socket properly fitted during repeated workshop and site jobs.
