Proto J4771A 1/4 Inch Drive 6-point Hand Socket

Product Description

The PROTO J4771A is a 6-point hand socket designed for 1/4 inch drive ratchets and extensions. Built from alloy steel with a chrome-plated finish, it accepts 1/4 inch fasteners and delivers solid engagement across flat-sided hex hardware. The 6-point geometry reduces the risk of rounding fastener corners compared to 12-point designs, making it a reliable choice for precision work in tight spaces. Overall length is 1.25 inches, keeping the profile compact for confined access points. This socket meets ASME B107.1 standards for hand socket tools and is suited for mechanics, maintenance technicians, and trade professionals working with small fasteners in instrumentation, electrical panels, and light mechanical assemblies.

The J4771A is appropriate for residential and commercial service applications where 1/4 inch drive tooling is standard. Its universal or flex socket type classification makes it compatible with 1/4 inch drive handles, ratchets, and torque wrenches of matching drive size. Typical use cases include HVAC control panel fasteners, electrical enclosure hardware, and small-component mechanical service where a compact, durable socket is needed. The chrome finish aids corrosion resistance during regular shop and field use.

Installation Notes

This socket is installed by licensed mechanics, HVAC technicians, electricians, and maintenance professionals using standard 1/4 inch drive hand tools. Always de-energize electrical equipment and isolate mechanical systems before breaking fasteners in live panels or pressurized assemblies. Inspect the socket for cracks or wear before each use. Do not use impact drivers with this hand socket unless it is rated for impact use.
