Proto J74287P Impact Socket 1/2 in Drive 1-1/4 in 6-pt

Product Description

The PROTO J74287P is a 6-point hex drive impact socket designed for heavy-duty fastening applications in professional trade environments. Built from alloy steel, it accepts a 1/2 inch drive and fits 1-1/4 inch fasteners. The 6-point contact geometry concentrates force on the flat faces of the fastener, reducing rounding and slippage under high-torque impact loads. At 3-13/64 inches overall length, the socket provides adequate reach for recessed fasteners while staying compact enough for tight workspaces. It meets ASME B107.2 standards, confirming dimensional and performance compliance for industrial use. Electricians, HVAC technicians, plumbers, and general mechanical contractors will find this socket suited to daily fastening work on equipment and structural components.

The J74287P is intended for use with 1/2 inch drive impact wrenches and ratchets in both residential and commercial service settings. Typical applications include equipment installation, mechanical assembly, and service work where 1-1/4 inch hex fasteners are common. The alloy steel construction handles the repeated shock loading produced by pneumatic and cordless impact tools without cracking or deforming under normal working conditions.

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive impact wrenches, air ratchets, and hand ratchets requiring a 1-1/4 inch 6-point hex socket.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with impact tooling and fastener torque requirements. Ensure the socket is fully seated on the drive anvil before applying torque to prevent ejection under load. Do not use impact sockets with hand-only torque tools beyond their rated capacity. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
