Proto J7012M Impact Socket 3/8 in Drive 12mm 6-pt

Product Description

The PROTO J7012M is a 12mm, 6-point impact socket designed for 3/8 inch drive impact wrenches and ratchets. Built for professional trade use, this socket delivers the torque transfer and wall thickness needed to withstand repeated impact cycles without rounding fasteners. The 6-point hex drive geometry seats fully on fastener flats, reducing slippage under high-torque conditions. With an overall length of 2-47/64 inches, it fits standard impact driver setups used by mechanics, industrial maintenance technicians, and assembly professionals on the floor or in the field.

This socket is suited for automotive, HVAC equipment service, mechanical assembly, and general industrial maintenance applications where a 3/8 inch drive impact tool is the primary driver. The 12mm size is common in metric fastener applications on equipment panels, compressor housings, fan assemblies, and structural hardware. Licensed tradespeople and experienced technicians in automotive and mechanical service will find this socket appropriate for daily production use in impact-rated applications.

Key Features

• 3/8 inch drive accepts standard 3/8 inch impact wrenches and ratchets
• 12mm 6-point hex drive geometry maximizes contact with fastener flats
• Overall length of 2-47/64 inches suits standard-depth fastener access
• Impact-rated construction handles repeated high-torque drive cycles
• Single-piece socket design with no moving parts for low-maintenance service life

Compatibility

Designed for use with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring a 12mm 6-point impact socket.

Installation Notes

Installation and fastener service with impact sockets should be performed by qualified mechanical or trade technicians familiar with torque requirements for the application. Always confirm the drive size of the tool matches the socket before use. Do not use impact sockets on non-impact manual-only drives without confirming the socket is rated for the application. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
