Gearwrench 80351 3/8 Drive 5/16 in 6 Point Hand Socket

Product Description

The GEARWRENCH 80351 is a standard-length 6-point hand socket designed for 3/8 inch drive ratchets and breaker bars. Built from alloy steel with a chrome-plated finish, it drives 5/16 inch fasteners with a hex drive interface. The 6-point design concentrates torque on the flat faces of the fastener, reducing the risk of rounding. At 0.984 inches in overall length, this is a standard-depth socket suited for general mechanical work. The tether-capable design supports drop prevention in elevated or safety-critical work environments. Licensed trades and general mechanics install this socket across automotive, HVAC, plumbing, and industrial maintenance applications.

This socket fits standard 3/8 inch drive tool sets and is appropriate for both residential and light commercial service work. The 5/16 inch size is common in sheet metal fastener applications, equipment access panels, and general mechanical assemblies. The tether-capable feature makes it suitable for work at height where tool drop is a safety concern, such as rooftop HVAC installations or elevated mechanical platforms. It meets ANSI and ASME B107.1 standards and is SAE-rated for inch-based fastener systems.

Compatibility

Compatible with standard 3/8 inch drive ratchets, breaker bars, and extensions. Designed for SAE inch-based fastener systems requiring a 5/16 inch socket.

Installation Notes

Install and remove using a 3/8 inch drive ratchet or breaker bar. Ensure the socket is fully seated on the fastener drive before applying torque to avoid slippage. When used in tethered applications, attach an approved tether lanyard to the tether point before use. Inspect the socket and drive square for wear before each use in high-torque applications.
