Proto J5412M 12mm 1/2 Drive 12-point Chrome Hand Socket

Product Description

The PROTO J5412M is a 12 mm, 12-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and torque wrenches. Built to standard length, it features a chrome-plated finish that resists corrosion and makes cleanup easier in shop environments. The 12-point design allows engagement at 30-degree increments, giving technicians more positioning options in tight spaces. This socket is suited for professional use in automotive, HVAC, plumbing, and general mechanical service work where precise fastener engagement and durability are required.

This socket fits typical 1/2 inch drive tool setups found in commercial and residential service vehicles and shop environments. It is well-suited for automotive repair, equipment maintenance, and mechanical installations where 12 mm fasteners are common. The standard length profile works with most drive handles without clearance issues in general-access applications.
