Proto J75418MP Impact Socket 1/2 in Drive 18mm 6-pt

Product Description

The PROTO J75418MP is a 6-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Built from alloy steel, it accepts an 18mm hex fastener and measures 3.5 inches overall length, making it suitable for a wide range of fastening applications in the field or shop. The 6-point geometry reduces rounding on worn fastener heads and provides reliable torque transfer under high-impact loads. Licensed tradespeople and professional mechanics rely on this socket for production-line work, fleet maintenance, and structural fastening tasks where a standard chrome socket would not hold up.

This socket fits residential, commercial, and industrial work environments wherever a 1/2 inch drive impact tool is in use. The universal style construction covers typical under-hood, chassis, and equipment assembly applications. At 0.68 pounds, it is light enough for overhead work while maintaining the material integrity required for impact-rated service. ASME specification B107.2 governs dimensional and performance requirements for this socket.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench or ratchet. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with hand-torque tools beyond their rated capacity. Always wear appropriate eye protection when operating impact tools.
