Gearwrench 81397 13 Pc 3/8 Drive 6 Point Sae Socket Set

Product Description

The GEARWRENCH 81397 is a 13-piece, 3/8 inch drive, 6-point standard socket set covering SAE sizes from 1/4 inch through 1 inch. Built from alloy steel with a full-polished chrome finish, these sockets deliver corrosion resistance and a clean surface that makes it easy to spot wear or damage. The 6-point design concentrates contact force on the flat faces of fasteners rather than the corners, reducing the chance of rounding under heavy torque. The set mounts on a rail for organized storage and quick access during service work. Mechanics, HVAC technicians, plumbers, and general tradespeople will find this range of sizes practical for everyday fastener work across a wide variety of equipment and assemblies.

This socket set is suited for maintenance and repair tasks in residential and commercial settings. The 3/8 inch drive is a common choice when working in moderate-torque applications where a 1/4 inch drive lacks the needed strength and a 1/2 inch drive is too bulky. Standard-depth sockets fit flat or slightly recessed fasteners and work efficiently in open or semi-open access areas. The full SAE range from 1/4 inch to 1 inch makes this set usable across mechanical, plumbing, HVAC, and electrical rough-in tasks that involve bolted connections.

Key Features

• 13-piece set with SAE sizes: 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1 inch
• 3/8 inch drive for balanced torque output in medium-duty applications
• 6-point geometry contacts fastener flats to reduce rounding risk
• Alloy steel construction for strength and durability under repeated use
• Full-polished chrome finish resists corrosion and simplifies cleaning
• Rail-mounted storage keeps sockets organized and prevents loss on the job

Compatibility

Designed for use with any standard 3/8 inch drive ratchet, extension, or torque wrench. Fits all common SAE hex fasteners within the 1/4 inch to 1 inch range.

Installation Notes

Ensure the ratchet or drive tool is fully seated in the socket square drive before applying torque. Inspect sockets for cracks or deformation before each use and remove any damaged socket from service. Do not use impact drivers with these chrome-finish hand-tool sockets unless the manufacturer explicitly rates them for impact use. Follow applicable workplace safety guidelines when working on mechanical assemblies under load or in confined spaces.
