Proto J75416MP Impact Socket 1/2 in Drive 16mm 6-pt

Product Description

The PROTO J75416MP is a 6-point impact socket designed for heavy-duty fastening and removal applications in professional trade environments. Built from alloy steel, it features a 1/2 inch drive and fits 16mm hex fasteners. The overall length measures 3.5 inches, and the socket conforms to ASME B107.2 standards, making it suitable for use in controlled torque applications. This socket is installed and used by mechanics, millwrights, electricians, plumbers, and HVAC technicians who require a reliable impact-rated socket for power tool use in the field or shop.

This socket is suited for residential, commercial, and industrial maintenance environments where 1/2 inch drive impact tools are standard. The 16mm size is common in mechanical and equipment service work, including HVAC unit assembly, pipe flange fastening, and electrical panel mounting. Its universal style and alloy steel construction hold up under repeated impact cycles from pneumatic or electric impact wrenches.

Key Features

• 6-point contact design reduces fastener rounding under high torque

Compatibility

Designed as an OEM-style replacement and general-use impact socket for 1/2 inch drive impact wrenches, torque wrenches, and ratchets accepting 16mm hex fasteners.

Installation Notes

Impact sockets should be used only with impact-rated drive tools. Do not use standard chrome hand-tool sockets with impact wrenches, as they are not rated for the shock loads involved. Inspect the socket for cracks or deformation before each use, and replace any damaged socket immediately. No special codes govern socket use, but general shop safety practices and PPE requirements apply.
