Proto J75276P Impact Socket 1/2 in Drive 9/16 in 6-point

Product Description

The PROTO J75276P is a 6-point impact socket designed for heavy-duty fastening and removal applications. Built from alloy steel, it accepts a 1/2 inch square drive and fits 9/16 inch hex fasteners. The socket measures 3-19/32 inches in overall length, giving it the reach needed for recessed or obstructed fastener heads. It meets ASME B107.2 standards, confirming dimensional and performance compliance for professional-grade impact use. This socket is installed by mechanics, millwrights, HVAC technicians, plumbers, and electricians who use 1/2 inch impact wrenches or ratchets for installation and service work.

The J75276P suits residential and commercial service applications where 9/16 inch fasteners appear on equipment panels, flanges, pipe fittings, mounting brackets, and structural hardware. Its 3-19/32 inch overall length accommodates moderately deep fastener access without requiring an extension in most standard installations. The alloy steel construction handles the repeated shock loading produced by pneumatic and cordless impact wrenches across demanding trade environments.

Key Features

• 6-point socket geometry reduces fastener rounding under high torque impact loads
• 1/2 inch square drive compatible with standard impact wrenches and ratchets
• Alloy steel construction rated for impact use and repeated shock loading
• Meets ASME B107.2 dimensional and performance standard
• 3-19/32 inch overall length for moderate-depth fastener access

Compatibility

Designed as an OEM-style replacement and service socket for use with 1/2 inch drive impact wrenches, air ratchets, and hand ratchets requiring a 9/16 inch 6-point socket.

Installation Notes

This socket is used by trade professionals across HVAC, plumbing, electrical, and mechanical service disciplines. Ensure the socket is fully seated on the drive anvil and fastener before applying impact force. 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-only torque tools beyond their rated capacity.
