Proto J5410 Hand Socket 5/16 Inch 12-point 1/2 Drive

Product Description

The PROTO J5410 is a 12-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and extensions. Built from alloy steel with a chrome-plated finish, it accepts 5/16 inch fasteners and measures 17/32 inches in overall length, placing it in the standard-length category. The 12-point configuration engages hex and double-hex fastener heads at 30-degree intervals, giving technicians more ratchet swing clearance in tight spaces. At 0.11 pounds, it is a lightweight single-piece tool suited for professional tool sets across mechanical, HVAC, plumbing, and electrical trades. It meets ASME B107.1 standards and carries a limited lifetime warranty.

This socket is a practical addition to any 1/2 inch drive set used in residential or commercial service work. The standard length makes it appropriate for general fastener removal and installation where clearance is not severely restricted. HVAC technicians, plumbers, electricians, and general mechanical service professionals will find this socket applicable to equipment panels, junction boxes, flanges, and mechanical fasteners commonly encountered in the field. The chrome finish resists corrosion and simplifies cleaning after use in oily or dirty environments.

Installation Notes

Install and remove by a qualified technician or experienced tradesperson using a compatible 1/2 inch drive tool. Ensure the socket is fully seated on the fastener head before applying torque to prevent rounding. Do not use impact-rated drivers with chrome hand sockets, as the chrome finish and socket geometry are not rated for impact use. Inspect the socket for cracks or deformation before each use and retire any damaged tool immediately.
