Proto J4739-27W Torx Bit Socket T27 1/4 in Drive

Product Description

The PROTO J4739-27W is a hand Torx bit socket designed for T27 fasteners. It accepts a 1/4 inch drive and measures 1.5 inches overall length (OAL). This socket is built for technicians and tradespeople who need precise, low-torque Torx fastener engagement in tight spaces. The T27 Torx profile delivers positive engagement with compatible fastener heads, reducing the risk of cam-out during removal or installation. It is a standard addition to any service toolkit where Torx hardware is encountered across HVAC equipment panels, electrical enclosures, and mechanical assemblies.

This socket suits residential and light commercial service applications where T27 Torx fasteners appear on equipment covers, control boards, and component brackets. The 1/4 inch drive sizing makes it compatible with standard 1/4 inch drive ratchets, extensions, and torque wrenches commonly found in HVAC, electrical, and general mechanical service kits. It is sold individually and is well-suited for field technicians adding specific Torx sizes to an existing drive set.

Key Features

Installation Notes

This is a hand socket intended for manual 1/4 inch drive use. Ensure the drive tool is rated for the torque required by the fastener application before use. Do not use with impact drivers unless the socket is impact-rated, which is not specified for this part. Follow applicable equipment manufacturer torque guidelines when securing panels or component hardware.
