Proto J47137S 37pc 1/4 Drive Sae Socket Set 6 Point

Product Description

The PROTO J47137S is a 37-piece SAE socket set built around a 1/4-inch drive and covering a size range from 1/8 inch through 9/16 inch. Each socket is machined to a 6-point configuration, which maintains full contact with fastener flats and reduces rounding on both standard and worn hardware. The set is suited for tight-space work common in HVAC equipment panels, electrical enclosures, and plumbing fixture access where a compact drive size is the practical choice. Licensed tradespeople and experienced service technicians working on equipment fasteners in the 1/8-to-9/16-inch range will find the full size progression useful for a single-tool approach to common hardware.

This socket set is well matched to service calls involving residential and light commercial equipment where 1/4-inch drive tooling is standard. The SAE sizing progression covers the fastener range found on sheet-metal enclosures, electrical panels, control-board mounting hardware, and small-bore plumbing fittings. The 6-point socket geometry is preferred on production and field work where fastener damage is a concern. The complete 37-piece set eliminates the need to carry multiple partial sets on a service vehicle.

Installation Notes

This set is intended for use by tradespeople familiar with fastener torque requirements for the equipment being serviced. Always de-energize electrical equipment and follow applicable lockout/tagout procedures before removing panel fasteners or accessing internal components. Use the correct socket size to avoid fastener damage; do not force an undersized socket onto a fastener. Inspect sockets for wear or cracking before use and replace damaged sockets before returning the set to service.
