Carlyle 3/8 Drive 4mm Hex 60mm Long Impact Socket (CISH3804M)

Description

Genuine Carlyle · Part no. CISH3804M

A 4mm hex impact socket, 60mm long, on a 3/8 inch drive. It is made from chrome molybdenum steel with a black phosphate finish, so it can run on an impact gun, and the long reach gets to small socket-head bolts sitting deep in a housing.

Good to know

• Should I use an impact gun on a 4mm hex? Only with care. A small hex is easy to strip; set the gun to its lowest setting, or break the bolt free by hand first.
• Why 60mm long? The length keeps the gun or ratchet clear of the surrounding parts when the bolt sits in a recess.
• What if the bit keeps slipping out? Check the bolt head is clean and that the bit is fully home. A bit that sits only part way in can round the head.

Which one?

The chrome CSH3804M is the 4mm for hand ratchets. For 3/8 inch impact hex sizes from 4mm to 12mm in one set, the Carlyle 7 Piece 3/8 Drive Hex Impact Socket Set 4mm to 12mm (CISS387HM) covers them.
