Proto J47102 Deep Socket Set 10 Pc 1/4 in Drive

Product Description

The PROTO J47102 is a 10-piece deep socket set built for professionals who need reach on recessed or deeply seated fasteners. The set runs on a 1/4 inch drive and covers sizes from 3/16 inch to 9/16 inch in fractional inch increments. All sockets are 6-point design, which delivers superior grip on hex fasteners and reduces rounding on worn hardware. A chrome finish provides corrosion resistance for daily shop and field use. The full set weighs 0.87 pounds, making it a compact addition to any service kit.

This deep socket set is suited for HVAC technicians, electricians, plumbers, and mechanical service pros working on equipment panels, motor mounts, control boxes, and other assemblies where standard-depth sockets cannot reach. The 1/4 inch drive size is ideal for lighter-duty fasteners in tight spaces. Ten sockets in a single set cover the most common fractional inch sizes encountered in residential and light commercial service work.

Key Features

• 10-piece set covers 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, and 9/16 inch sizes
• 1/4 inch drive compatible with standard 1/4 inch ratchets, extensions, and adapters

Compatibility

Designed for use with any standard 1/4 inch drive ratchet, breaker bar, or extension. Sized in fractional inch increments for use on inch-standard fasteners typical in residential and light commercial HVAC, plumbing, and electrical equipment.

Installation Notes

Always de-energize electrical equipment and shut off applicable utilities before accessing fasteners in service panels or equipment enclosures. Use the correct socket size to avoid rounding fastener heads. Inspect sockets for cracks or wear before use and replace damaged sockets immediately. Follow applicable local codes and manufacturer service procedures when disassembling equipment.
