Proto J77516MP Impact Socket 3/8 in Drive 16mm

Product Description

The PROTO J77516MP is a 16mm 12-point impact socket with a 3/8 inch drive, built for use with pneumatic and electric impact wrenches in professional trade environments. Constructed from alloy steel, it delivers the toughness required for high-torque fastening and removal tasks. The 12-point design allows engagement at multiple angles, reducing the need to reposition in tight access areas. At 2-3/32 inches overall length, it fits standard impact tool setups across automotive, mechanical, and industrial applications. This socket meets ASME B107.2 specifications, confirming it is manufactured to recognized dimensional and performance standards for impact-rated hand tools.

This socket is suited for automotive repair shops, fleet maintenance facilities, and industrial assembly environments where metric fasteners are common. The 3/8 inch drive size makes it a practical choice for mid-range torque applications where a 1/2 inch drive would be excessive. Technicians working on engine components, suspension assemblies, and general equipment maintenance will find this socket appropriate for daily high-cycle use. Its universal style designation indicates broad fitment across standard 3/8 inch drive impact wrenches and ratchets.

Compatibility

Designed as an OEM-style impact socket for use with standard 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring a 16mm metric socket.

Installation Notes

This socket is installed and used by automotive technicians, industrial mechanics, and maintenance professionals. Always verify the drive size of the impact tool matches the socket drive before use. Do not use impact sockets on non-impact hand tools beyond their rated torque capacity, and inspect the socket for cracks or deformation before each use. Refer to applicable ASME and shop safety standards for proper tool handling procedures.
