Description

Genuine Carlyle · Part no. CSH3804M

Carlyle's CSH3804M is a 4mm hex bit socket on a 3/8 inch square drive, for 4mm socket-head screws and bolts. It has an S2 steel bit held in a chrome-plated socket with a knurled band, and runs on a 3/8 inch ratchet or torque wrench.

Good to know

Why a bit socket rather than an L-key? A ratchet gives better control and lets you work faster on a run of screws, and a torque wrench can be fitted when a figure is given.
How tight should I go with 4mm? Not very. A small hex screw needs only modest force; over-tightening strips the head or the thread.
Is it for impact use? No. It is chrome hand tooling; the impact version is the black CISH3804M.

Which one?

For an impact gun, the CISH3804M is the 4mm impact socket. For a hex bit set with a storage rail, the Carlyle Socket Set – Hex Bit Metric Size Various (BSH3812M) covers the metric sizes.
