Description
Genuine Carlyle · Part no. SH3804M
The SH3804M is a 4mm hex bit socket on a 3/8 inch square drive, for 4mm socket-head screws and bolts. It pairs an S2 steel bit with a chrome vanadium socket finished in mirror chrome to keep rust off, and suits 3/8 inch ratchets and torque wrenches.
Good to know
- Why choose a bit socket over a 4mm Allen key? A ratchet turns a row of screws faster and with better control, and a torque wrench can go on when there is a figure to meet.
- How tight should a 4mm screw be? Not very. Small hex screws strip their heads or threads easily, so stop at firm unless the manual gives a figure.
- Can I use it in an impact driver? No, it is a chrome hand socket.
Which one?
The CSH3804M in our range is a similar 4mm with a knurled band, and the CISH3804M is the 4mm impact version. For a rail set of metric hex bits, see the Carlyle Socket Set – Hex Bit Metric Size Various (BSH3812M).
