Proto J74417MP Impact Socket 1/2 in Drive 17mm 6-pt

Product Description

The PROTO J74417MP is a 6-point impact socket designed for heavy-duty fastening and removal applications. Built from alloy steel, it accepts a 1/2 inch drive and fits 17mm hex fasteners. The socket measures 2-11/16 inches overall length and is rated to the ASME B107.2 specification, confirming it meets established performance and dimensional standards for impact-rated hand tools. It is intended for use with 1/2 inch drive impact wrenches and ratchets in professional trade environments where torque output and tool durability are critical. Technicians across HVAC, plumbing, electrical, and general mechanical service will find this socket a dependable addition to their drive set.

This socket is suited for residential and commercial service work where 17mm fasteners appear on equipment panels, mechanical connections, conduit fittings, pump flanges, and structural hardware. The 6-point design concentrates drive force on the flat faces of the fastener, reducing the chance of rounding under high torque. The universal style designation indicates broad applicability across standard metric fastener applications in a shop or field setting.

Installation Notes

This socket is installed and removed by hand on any compatible 1/2 inch square drive tool. Before using an impact socket for fastener removal on energized or pressurized systems, de-energize electrical circuits per NFPA 70E guidelines or shut off and depressurize fluid systems per applicable codes before breaking fasteners. Do not use impact sockets with non-impact hand ratchets in applications that exceed the rated torque of the hand tool. Inspect the socket for cracks or deformation before each use and replace if damage is found.
