Deep Impact Socket 40mm 3/4in Drive 6 Point CR-MO 90mm

A 40mm deep impact socket with a 3/4in drive, made for larger fasteners where standard sockets may not reach far enough. The deep pattern and 90mm length make it useful when working over longer studs, while the 6-point shape gives solid contact on the nut or bolt.

Used across garages, workshops, plant maintenance and general mechanical repair, this 40mm impact socket suits heavier fastening jobs where proper engagement matters. It can be used with manual tools or an impact wrench, so it works well for vehicle maintenance, machinery servicing and repair work involving larger nuts and bolts. When access is tight around deeper fixings, the extra depth helps you get onto the fastener more cleanly than a shallow socket.

This CR-MO socket is built for impact use and suited to repeated workshop and maintenance work. The 3/4in drive fits the matching size of ratchet, breaker bar or impact wrench, and the socket can be secured to an impact wrench with a pin and O-ring where required. At 90mm overall height, it gives added reach without becoming overly awkward to handle, which is useful when working on recessed fasteners or studs that protrude beyond the nut. The 6-point profile also helps maintain a firmer fit on the flats of the fastener, which is especially useful on larger fixings that need steady contact.
