Proto J4718 Hand Socket 9/16 in 6-point 1/4 in Drive

Product Description

The PROTO J4718 is a 6-point hand socket designed for precision fastener work in mechanical, electrical, and HVAC service applications. Sized at 9/16 inch with a 1/4 inch square drive, this standard-length socket is machined from alloy steel and finished with a chrome plating for corrosion resistance and durability. The 6-point geometry provides maximum contact with hex fastener faces, reducing the risk of rounding under torque. Overall length is 7/8 inch. At 0.07 pounds, it is a compact, lightweight tool suited for tight-clearance installations where a smaller drive size is appropriate. Licensed tradespeople and service technicians will find this socket a reliable addition to a 1/4 inch drive set.

The J4718 is well-suited for low-torque fastener applications commonly encountered in HVAC service panels, electrical enclosures, plumbing fixture hardware, and light mechanical assemblies. The 1/4 inch drive size is a standard choice when working in confined spaces where a full 3/8 inch or 1/2 inch drive ratchet would be impractical. Its standard-length profile keeps the tool manageable in recessed or partially obstructed fastener locations. This socket meets AS4984A and ASME B107.110-2012 standards, confirming dimensional and performance compliance for professional use.

Key Features

Compatibility

Designed for use with standard 1/4 inch drive ratchets, extensions, and torque wrenches accepting 6-point hand sockets.

Installation Notes

This socket is intended for use by qualified technicians working on mechanical, HVAC, or electrical equipment. Always de-energize and lock out electrical systems before using hand tools in electrical enclosures. Use with a calibrated torque wrench where fastener torque specifications are required by the equipment manufacturer or applicable code. Inspect the socket for cracks or wear before each use and replace if the drive or socket opening shows signs of deformation.
