The Stanley STMT88930-8B 1/2Inch Extension Bar is a professional socket accessory designed to extend the reach of a compatible 1/2-inch drive ratchet, breaker bar or other suitable drive tool. With a 75mm (3-inch) overall length, it helps users access nuts and bolts positioned deeper inside assemblies or in areas where a standard socket may not provide sufficient reach. Stanley's socket catalogue specifically identifies the STMT88930-8B as a 1/2-inch, 75mm extension.

Constructed from chrome vanadium steel, the extension bar is designed to withstand regular manual fastening and loosening operations. Its fully polished finish provides a smooth surface that is easier to clean after workshop use. Current product specifications also identify the tool as intended for manual use and manufactured to relevant socket-accessory standards.

The extension bar connects between the 1/2-inch drive tool and socket, increasing the effective reach of the socket. This is particularly useful when working around recessed fasteners, engine components, machinery assemblies and other restricted-access areas.

Wide Application Details

The Stanley STMT88930-8B is suitable for automotive repair, mechanical maintenance, machinery servicing, workshop applications, equipment assembly, industrial maintenance and general fastening work. It is especially useful when additional socket reach is required without changing the drive size.
