Proto J74277P 1/2 in Drive 5/8 in 6-point Impact Socket

Product Description

The PROTO J74277P is a 6-point impact socket designed for use with 1/2 inch drive impact wrenches and rattle guns. It accepts a 5/8 inch hex fastener and is built from alloy steel for the toughness required in high-torque impact applications. The overall length is 2-19/32 inches, keeping it compact enough for close-quarter work while maintaining full engagement on the fastener. This socket meets ASME B107.2 standards, making it appropriate for professional use in HVAC, plumbing, electrical, and general mechanical service. Licensed tradespeople and experienced technicians are the primary users.

This socket is suited for residential and commercial service work where 1/2 inch drive impact tools are standard. It handles fasteners in equipment panels, mechanical connections, and structural mounting hardware. The universal style and 6-point geometry reduce the risk of rounding fastener heads under high torque, which matters in field conditions where fasteners may be corroded or over-tightened from the factory. It fits standard 1/2 inch drive impact guns and manual ratchets.

Key Features

• 6-point socket geometry for maximum contact and reduced fastener rounding
• 1/2 inch square drive compatible with standard impact wrenches and manual ratchets
• 5/8 inch hex drive size for common fastener applications
• Alloy steel construction rated for impact use
• Meets ASME B107.2 specification for impact sockets
• Compact 2-19/32 inch overall length for tight-space access

Compatibility

Designed as an OEM-style replacement and general-service impact socket for use with any standard 1/2 inch drive impact wrench or ratchet accepting 5/8 inch hex fasteners.

Installation Notes

This socket is installed and removed by hand onto the drive anvil of a 1/2 inch impact wrench or ratchet. Always confirm the socket is fully seated on the drive before applying torque. Do not use impact sockets on non-impact hand ratchets beyond their rated torque range, and never use standard chrome sockets in place of impact-rated sockets with pneumatic or electric impact tools. No special tools or trade licensing are required for socket use, though the fastener application itself may require licensed trade work.
