The APEX 80157 is a 1/4 inch drive hex bit socket designed for driving and removing internal hex fasteners in trade and industrial applications. The base socket is constructed from heat-treated alloy steel for structural durability and extended service life. The hex bit itself is manufactured from S2 tool steel, which provides high impact and torque resistance under repeated use. At 1.53 inches in length and 0.05 pounds, this compact socket fits standard 1/4 inch drive ratchets and extensions. It is sized for 5/32 inch SAE hex fasteners and is sold individually.
This bit socket is suited for mechanical, electrical, HVAC, and plumbing service work where internal hex fasteners are commonly encountered on equipment panels, valve assemblies, motor mounts, and access covers. The 5/32 inch SAE size addresses a fastener specification found frequently in light commercial and residential equipment. Technicians in multiple trades keep this socket size on hand for recurring service calls involving hex-head set screws and cap screws.
Designed as a standard 1/4 inch drive SAE hex bit socket suitable for use with any 1/4 inch drive ratchet, torque wrench, or extension bar.
This socket is installed and used by technicians across the mechanical trades. Always ensure the drive tool and socket are fully seated before applying torque to avoid rounding fastener heads. Inspect the bit tip for wear before use on critical fasteners. Keep drive tools and sockets clean and free of debris to maintain proper engagement.
