Product Description

The PROTO J7016M is a 16mm, 6-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. Built for professional tradespeople, this socket delivers reliable torque transfer in high-stress fastening applications. The 6-point contact geometry reduces the risk of rounding fasteners under impact load. At 2-47/64 inches overall length, it fits standard impact tool setups without excessive extension. Weighing 0.29 pounds, it is a durable, compact tool suitable for mechanical, electrical, plumbing, and HVAC service work where metric fasteners are common.

This socket is suited for residential and commercial service environments where 16mm metric fasteners are encountered. Typical applications include equipment installation, panel and bracket fastening, and general mechanical assembly. It is compatible with 3/8 inch drive impact wrenches, cordless impact drivers with proper adapters, and manual ratchets. Technicians in HVAC, electrical, and plumbing trades commonly carry metric impact sockets in this size range for equipment service and rough-in work.
