Proto J7416M Impact Socket 1/2 in Drive 16mm 6-point

Product Description

The PROTO J7416M is a 16mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Built for heavy-duty fastener work, it delivers reliable torque transfer in professional mechanical, industrial, and trade applications. The hex drive profile and 6-point geometry provide maximum contact on fastener flats, reducing the risk of rounding under high-torque impact conditions. At 1.5 inches overall length, it fits in standard socket sets and works well in moderate-clearance applications. Weighing 0.2 pounds, it is compact and suited for technicians who need a dependable metric impact socket for production or field service work.

This socket is appropriate for automotive repair, fleet maintenance, heavy equipment service, and general mechanical work where a 16mm fastener and 1/2 inch drive impact tool are required. It is well suited for professional mechanics, HVAC technicians working on equipment fasteners, and industrial maintenance trades. The 6-point design is preferred for impact use over 12-point sockets because it concentrates force across the full flat of the fastener, making it the correct choice for high-torque or stubborn fastener removal.

Key Features

• 1/2 inch drive size compatible with standard impact wrenches and ratchets
• 16mm socket size for metric fastener applications
• 6-point hex drive geometry maximizes contact and reduces fastener rounding under impact
• 1.5 inches overall length suits moderate-clearance work environments
• Lightweight at 0.2 pounds for reduced hand fatigue during extended use

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive impact wrenches, air tools, and ratchets accepting standard square drive sockets.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench or ratchet. Always confirm the socket is fully seated on the fastener before applying torque. Power down or de-energize any electrically driven equipment before accessing fasteners in electrical or HVAC enclosures. Do not use impact sockets with hand-drive torque wrenches, as impact-rated sockets are not calibrated for precision torque applications.
