3/8 in Drive Hex Socket Bit Metric 9 mm Tip, 2 23/32 in L, 3/8" Dr, 9mm Hex Socket Bit, Tether Ready

This Proto Tethered Tool Socket is a reliable and secure solution for heavy-duty applications. The 3/8 in drive hex socket bit features a 9mm tip and 2 23/32 in length, making it ideal for working with metric fasteners.

Suitable for use in industries such as construction, manufacturing, and maintenance, this socket is perfect for applications that require high torque and secure fastening.

Top product features:
