Proto J5230N 15/16 Inch 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5230N is a 15/16 inch, 12-point intermediate hand socket designed for professional mechanical and industrial use. Built from polished steel, this 3/8 inch drive socket meets ASME B107.21 standards and is suited for fastener work in tight or standard clearance applications. The 12-point geometry provides multiple engagement positions on hex fasteners, reducing the need to reposition the socket in confined spaces. At 1-47/64 inches overall length, it fits the standard length category and delivers the durability trade technicians expect from a professional-grade hand tool.

This socket is appropriate for use in automotive, mechanical maintenance, HVAC equipment service, and general industrial applications where a 3/8 inch drive ratchet or breaker bar is the tool of choice. It is well suited for service technicians, maintenance mechanics, and journeymen who need reliable fastener engagement in day-to-day hands-on work. The polished finish aids in visual inspection and resists surface corrosion during normal shop use.
