Proto J4710L Deep Hand Socket 5/16 in 6-point 1/4 Drive

Product Description

The PROTO J4710L is a deep hand socket designed for 1/4 inch drive ratchets and extensions. Built to a 5/16 inch socket size with a 6-point contact pattern, it delivers a secure grip on fastener flats, reducing the risk of rounding. The chrome-plated finish resists corrosion and makes the socket easy to clean after use. This is a standard hand-tool socket suited for professional mechanics, maintenance technicians, and tradespeople who need reach into recessed fastener locations where a standard-depth socket will not seat properly.

The J4710L is appropriate for general mechanical and maintenance work across residential, commercial, and light industrial settings. Its deep-length profile is especially useful when driving nuts on long bolt shanks, threaded rod, or in applications where a fastener sits well below a surrounding surface. Licensed tradespeople in HVAC, plumbing, electrical, and facilities maintenance commonly carry deep socket sets in 1/4 inch drive for panel work and equipment service.

Designed as an OEM-style replacement and standard fit for use with 1/4 inch drive ratchets, extensions, and torque wrenches that accept standard square-drive sockets.

Installation Notes

Hand socket installation and removal requires no special certifications, but correct drive size matching between socket and ratchet is essential before applying torque. Ensure the socket seats fully onto the fastener before turning to prevent slipping. Do not use hand sockets with impact drivers unless the socket is rated for impact use. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
