Proto J47701/8B Hand Hex Bit Socket 1/4 in Drive

Product Description

The PROTO J47701/8B is a ball end hand hex bit socket designed for use with 1/4 inch drive tools. It accepts a 1/8 inch hex fastener and features a ball end tip that allows engagement at up to a 25-degree offset from the fastener axis. Overall length is 1.5 inches with a bit length of 1.047 inches. This socket is used by maintenance technicians, electricians, HVAC techs, and plumbers when working in tight or angled access points where a straight-on approach is not possible.

This socket fits standard 1/4 inch drive ratchets, extensions, and T-handles. The ball end design is well suited for light-duty fastening and loosening in confined spaces, such as panel interiors, equipment enclosures, and mechanical assemblies. It is sized for 1/8 inch hex fasteners, which are common in instrumentation, small valves, and set screw applications encountered in trade and industrial maintenance work.
