Gearwrench 80544 Hex Bit Socket 3/8 in Drive 5/16 in Ball End

Product Description

The GEARWRENCH 80544 is a ball end hand hex bit socket designed for use with 3/8 inch drive ratchets and extension bars. It accepts a 5/16 inch hex fastener and features a ball end design that allows engagement at off-axis angles, useful when working in tight or obstructed spaces. The overall length is 2 inches, with a bit length of 1.181 inches. Constructed from steel with a chrome finish, this socket is built for repeated use in professional shop and field environments. Licensed mechanics, maintenance technicians, and general trade professionals will find this socket useful for hex-head fastener work across a wide range of applications.

This socket is suited for automotive, HVAC equipment, electrical panel assemblies, and general mechanical maintenance tasks where 5/16 inch hex fasteners are encountered. The ball end geometry allows the socket to engage fasteners at up to approximately 15 degrees off-center, reducing the need to reposition the tool in confined areas. It is packaged and sold individually and is compatible with any standard 3/8 inch drive tool set.

Compatibility

Designed for use with any standard 3/8 inch drive ratchet, breaker bar, or extension. Fits 5/16 inch ball end hex fasteners in automotive, mechanical, and general trade applications.

Installation Notes

Install and remove using a 3/8 inch drive ratchet or torque wrench. Ensure the fastener head is fully seated in the socket before applying torque to prevent rounding. When using the ball end engagement angle, avoid maximum torque applications at extreme off-axis positions, as this can accelerate socket and fastener wear. Inspect the socket for cracks or wear before each use.
