Facom 1/2" Drive Hex Socket-8mm (STM.8).....chrome bit holder with non-removable bit. Overall length = 60mm.

The FACOM STM.8 is a premium, standard-length 1/2-inch square drive metric 8 mm hexagon bit socket. It is engineered to deliver high torque transfer directly into internal hex (Allen) socket head screws, minimizing the risk of slippage or rounded bolt heads compared to standard L-keys.  The socket body is finished in bright polished chrome to resist corrosion, while the non-removable bit features a high-durability, phosphate-hardened finish designed to withstand heavy workshop wear.
