Proto J49909/64 Hex Bit Socket 3/8 in Drive 9/64 in

Product Description

The PROTO J49909/64 is a hand hex bit socket designed for fastening and loosening hex fasteners in professional trade applications. It features a 3/8 inch drive and accepts a 9/64 inch hex bit, with an overall length of 1.625 inches. Constructed from chrome-finished steel, this socket delivers the durability and corrosion resistance required in demanding service environments. It meets ASME B107.100-2010 standards, confirming dimensional and performance compliance for professional-grade hand tools. Electricians, HVAC technicians, plumbers, and general mechanical trades rely on sockets like this for routine fastener work on equipment panels, fittings, and mechanical assemblies.

This hex bit socket is suited for use in residential and light commercial service environments where 3/8 inch drive tooling is standard. It fits standard 3/8 inch drive ratchets, extensions, and breaker bars. The 9/64 inch hex size targets smaller fasteners commonly found in equipment enclosures, motor mounts, and access panels. The compact 1.625 inch overall length makes it practical in tighter spaces where longer sockets would be difficult to maneuver.
