Proto J47701/16 Hex Bit Socket 1/4 in Drive

Product Description

The PROTO J47701/16 is a hand hex bit socket designed for manual fastener driving in tight or precision applications. It accepts a 1/4 inch square drive and engages 1/16 inch internal hex fasteners. The overall length is 1-7/8 inches, with a bit length of 1 inch, making it a compact tool suited for close-quarter work. This socket is used by electricians, plumbers, HVAC technicians, and mechanical service pros who work with hex-head machine screws, set screws, and similar fasteners in equipment panels, valve assemblies, and mechanical linkages.

This hex bit socket fits standard 1/4 inch drive hand tools including ratchets, T-handles, and extension bars. The 1/16 inch hex size is commonly found on small set screws and fasteners used in control components, motor assemblies, and precision mechanical hardware. It is appropriate for both residential and light commercial service work where small-format hex fasteners are encountered during installation or maintenance tasks.

Installation Notes

Install and remove fasteners by hand using a compatible 1/4 inch drive ratchet or T-handle. Ensure the drive tool and socket are fully seated before applying torque to avoid rounding small hex fasteners. Disengage power or de-energize equipment before accessing fasteners inside electrical panels or mechanical enclosures. This tool is intended for hand-drive use only and is not rated for impact driver applications.
