Proto J5316 Deep Hand Socket 1/2 in 12-point Chrome

Product Description

The PROTO J5316 is a 12-point deep hand socket designed for 1/2 inch drive ratchets, breaker bars, and extensions. It accepts 1/2 inch fasteners and delivers the reach needed to seat fully on recessed or stacked hardware. Built from alloy steel with a chrome-plated finish, the J5316 resists corrosion and cleans up easily in shop environments. At 3.25 inches overall length, it provides the clearance required for deep-set bolts and studs common in HVAC equipment, piping assemblies, and mechanical installations. Meets ASME B107.110-2012 and SAE AS954G standards. Suitable for use by licensed mechanics, HVAC technicians, plumbers, and industrial maintenance trades.

The J5316 is used wherever a standard-length socket cannot reach — recessed fasteners on blower assemblies, flange bolts, motor mounts, and structural hardware in mechanical and electrical equipment. The 12-point design engages fasteners at more positions than a 6-point, making it practical in tight quarters where full rotation of the drive handle is limited. Appropriate for both shop bench work and field service calls requiring reliable hand-tool access to deep fastener locations.

Key Features

• 1/2 inch drive accepts standard 1/2 inch drive ratchets, torque wrenches, and extensions
• 1/2 inch socket size fits 1/2 inch fasteners precisely
• 12-point design allows engagement at multiple positions in restricted swing areas
• Deep length at 3.25 inches overall reaches recessed and stacked fastener applications
• Alloy steel construction with chrome-plated finish for corrosion resistance and durability
• Meets ASME B107.110-2012 and SAE AS954G standards for hand socket tools

Compatibility

Designed as a standard 1/2 inch drive deep hand socket compatible with any 1/2 inch drive ratchet, torque wrench, breaker bar, or extension bar conforming to standard drive tolerances.

Installation Notes

Install and remove fasteners only with the drive tool fully seated in the socket and the socket fully engaged on the fastener. De-energize or de-pressurize equipment before servicing fasteners on live electrical panels, pressurized piping, or HVAC refrigerant circuits. Do not use impact drivers with this hand socket unless the socket is rated for impact use. Inspect the socket for cracks or wear before each use and replace if drive or point wear is visible.
