Proto J74285P Impact Socket 1/2 in Drive 1-1/8 in 6-pt

Product Description

The PROTO J74285P is a 6-point impact socket designed for heavy-duty fastening and removal work. Built from alloy steel, it accepts a 1/2 inch square drive and fits 1-1/8 inch hex fasteners. The 6-point contact geometry reduces the risk of rounding fastener corners under high torque, making it a reliable choice for production, maintenance, and service work. At 3 inches overall length, it provides adequate clearance for most standard fastener applications. This socket is intended for use with 1/2 inch drive impact wrenches and is suited for mechanics, HVAC technicians, plumbers, and other trade professionals who work with pneumatic or electric impact tools.

The J74285P fits typical applications where 1-1/8 inch hex fasteners are encountered on mechanical equipment, HVAC systems, plumbing fixtures, and structural assemblies. Its universal style and alloy steel construction make it appropriate for both shop and field use. This socket is sold individually and is compatible with standard 1/2 inch drive impact wrenches and ratchets. It meets ASME B107.2 specifications, confirming dimensional and performance standards appropriate for professional trade use.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench or ratchet. Ensure the socket is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with standard hand-torque tools where impact rating is not required, and do not use hand sockets with impact tools.
