Proto J7316M Impact Socket 1/2 in Drive 16mm 6-pt

Product Description

The PROTO J7316M is a 6-point impact socket designed for use with 1/2 inch drive impact wrenches. It accepts a 16mm fastener and delivers a hex drive interface with an overall length of 3.25 inches. Built for the demands of professional trades, this socket handles the torque output of pneumatic and electric impact tools without deforming under load. Electricians, mechanics, HVAC technicians, and plumbers reach for impact-rated sockets when working with heavy fasteners on equipment installations, service disconnects, and mechanical assemblies. The 6-point design concentrates force on flat fastener surfaces, reducing the risk of rounding corners on seized or heavily torqued hardware.

This socket suits residential and commercial service work wherever a 1/2 inch drive impact tool is standard. Common applications include equipment mounting, conduit support hardware, structural fasteners, and mechanical room installations. The 16mm size is frequently encountered on metric-fastened HVAC equipment, pump assemblies, and electrical enclosure hardware. With a 3.25 inch overall length, this socket provides added reach for recessed or obstructed fastener locations without requiring an extension in many situations.

Key Features

• 1/2 inch drive fits standard impact wrenches and ratchets
• 16mm socket size for metric fastener applications
• 6-point hex drive reduces fastener rounding under high torque
• 3.25 inch overall length provides reach into recessed fastener locations
• Impact-rated construction handles pneumatic and electric impact tool output

Compatibility

Designed as an OEM-style replacement or service addition compatible with standard 1/2 inch drive impact wrenches, torque wrenches, and ratchets accepting 16mm metric sockets.

Installation Notes

This socket is installed and removed by hand when changing between fastener sizes — no special tooling is required. Always verify the drive tool is powered down or depressurized before swapping sockets on pneumatic impact wrenches. Use only impact-rated sockets with impact drivers; chrome hand-socket alloys are not rated for impact tool torque and may fracture. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
