Proto J77275P Impact Socket 3/8 in Drive 1/2 in Hex

Product Description

The PROTO J77275P is a 6-point hex drive impact socket designed for high-torque fastening and removal applications. Built from alloy steel, it accepts a 3/8 inch drive and fits 1/2 inch fasteners with an overall length of 2 inches. The universal style and hex drive configuration make it suitable for use with impact wrenches and air tools in demanding service environments. This socket meets ASME B107.2 standards, confirming dimensional accuracy and material integrity. Technicians in HVAC, plumbing, electrical, and mechanical trades rely on impact-rated sockets like this one when standard chrome sockets are not appropriate for high-impact use.

The J77275P fits standard impact wrench setups using a 3/8 inch square drive. The compact 2-inch overall length suits confined spaces where a longer socket would interfere with surrounding components. Its 6-point contact geometry reduces the likelihood of rounding fastener heads compared to 12-point designs, making it a practical choice for rusted or corroded fasteners common in field service work. Suitable for residential and light commercial maintenance tasks across multiple trades.

Key Features

• Alloy steel construction rated for impact tool use
• 6-point hex drive reduces fastener rounding under high torque
• 3/8 inch drive fits standard impact wrenches and ratchets
• 1/2 inch socket size for common fastener applications
• 2 inch overall length for use in tighter spaces
• Meets ASME B107.2 dimensional and material standards

Compatibility

Designed as an OEM-style impact socket compatible with 3/8 inch drive impact wrenches and ratchets accepting standard square drive tooling.

Installation Notes

Impact sockets should only be used with impact-rated tools and drives. Inspect the socket for cracks or deformation before each use, as impact fatigue can cause sudden failure. Always ensure the socket is fully seated on the fastener before applying torque. Do not use impact sockets with hand-drive torque wrenches, as shock loading can damage calibration.
