Proto J5016M Deep Hand Socket 16mm 3/8 Drive 12-point

Product Description

The PROTO J5016M is a 16 mm deep hand socket built for professional hand-tool use in mechanical, automotive, and industrial service applications. It runs on a 3/8 inch drive and features a 12-point configuration, giving technicians the flexibility to engage fasteners from multiple angles in tight spaces. The chrome-plated finish resists corrosion and simplifies cleanup after use. At 2.8 inches in length, the deep profile reaches recessed fasteners that standard-length sockets cannot access. This socket meets ASME B107.5 standards, confirming it is manufactured to recognized tool-quality specifications.

This socket is suited for professional use in automotive shops, HVAC service, plumbing rough-in, and general mechanical maintenance where metric fasteners are common. The deep well profile is especially useful when working with long bolt studs or fasteners seated below a surface. The 3/8 inch drive makes it compatible with mid-range ratchets and torque wrenches commonly found in professional tool sets.

Installation Notes

Install and remove with a 3/8 inch drive ratchet or torque wrench rated for the fastener application. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding. Inspect the socket for cracks or wear before each use and remove from service if damage is found. No power-tool or impact use is specified for this hand socket.
