Proto J4739-20W T20 Torx Bit Socket 1/4 Inch Drive

Product Description

The PROTO J4739-20W is a hand Torx bit socket designed for T20 fastener drive applications in professional tool kits. Built on a 1/4 inch drive, this socket measures 1.5 inches in overall length (OAL), making it a compact option for working in tighter spaces. It is intended for use with a standard 1/4 inch drive ratchet or handle and provides a direct, secure engagement with T20 Torx fasteners. Technicians across HVAC, plumbing, electrical, and general mechanical trades rely on Torx bit sockets when working with equipment panels, motor housings, and control enclosures that use Torx-head fasteners.

This socket is suited for both residential and light commercial service work where T20 Torx fasteners are encountered. Common applications include panel removal on HVAC equipment, access cover fasteners on electrical enclosures, and equipment assembly or disassembly tasks that require a 1/4 inch drive tool. The compact OAL allows use in areas where a longer socket would limit clearance. It is sold individually and is compatible with standard 1/4 inch drive hand tools.

Installation Notes

This socket is intended for use by qualified trade professionals working with hand tools. Before servicing any equipment, ensure power is off and all energy sources are locked out per applicable OSHA lockout/tagout procedures. Use only with 1/4 inch drive ratchets or handles rated for hand-tool torque applications. Do not use with impact drivers unless the socket is specifically rated for impact use.
