6PT flank socket 3/8" metric

This category contains 6-point sockets with a 3/8" drive in metric sizes. The range includes sizes 6 mm to 20 mm, among others.

A 6-point socket engages the six flats of a nut or bolt head, giving you a firm grip. The 3/8" drive is a versatile size for general work in the workshop and garage. The same sockets are also available in imperial (SAE) sizes.

The sockets are made by Seneca and come in a professional version. You use them with a ratchet or another tool with a 3/8" drive.
