The PROTO J4739-10W is a hand Torx bit socket designed for T10 fasteners. It features a 1/4 inch square drive and measures 1.5 inches overall length. The socket is built for professional hand-tool use in tight or confined fastener locations where a standard Torx driver or impact tool may not be appropriate. Technicians across HVAC, electrical, plumbing, and general mechanical service use T10 Torx bit sockets when working with OEM fasteners found on equipment panels, motor housings, and control enclosures.
This socket suits residential and light commercial service applications where T10 Torx fasteners are common on access panels, blower compartments, and control board covers. The 1/4 inch drive sizing is compatible with standard 1/4 inch drive ratchets, extensions, and adapters found in most trade tool sets. It is sold individually, making it a practical replacement or addition to an existing socket set.
Designed for use with standard 1/4 inch drive hand tools and compatible with T10 Torx fasteners found on a wide range of HVAC equipment panels, electrical enclosures, and mechanical assemblies.
This socket is intended for hand-tool use only and should not be used with impact drivers or pneumatic tools unless the tool is specifically rated for impact use. Ensure the drive connection is fully seated in the ratchet or extension before applying torque. When servicing equipment, shut off all power at the disconnect or breaker before removing fastened panels or covers. Follow all applicable safety and service procedures required by the equipment manufacturer.
