Proto J7420HF Impact Socket 1/2 in Drive 5/8 in 6-point

Product Description

The PROTO J7420HF is a 6-point impact socket designed for 1/2 inch drive impact wrenches and rattle guns used in mechanical, HVAC, and industrial service work. Built from alloy steel with a magnetic design to retain fasteners during positioning, it accepts a 5/8 inch hex fastener and measures 1.5 inches overall length. The short profile suits tight-clearance applications where a standard-length socket would foul against surrounding components. Licensed mechanics, HVAC technicians, and pipefitters working with hex-head bolts and fittings will find this socket a reliable addition to a professional impact set.

This socket is suited for residential and commercial service environments where 5/8 inch hex fasteners appear on equipment panels, flanges, mounting hardware, and structural connections. The 6-point contact geometry reduces corner rounding on fasteners compared to 12-point designs, making it preferable for high-torque impact use. The magnetic feature holds the socket onto the fastener during overhead or awkward-angle work, reducing drop risk. It is equally at home on a production floor or a field service truck.

Key Features

• 6-point contact reduces fastener rounding under high-torque impact loads
• Magnetic design retains fasteners during positioning and overhead work
• Alloy steel construction resists impact stress and wear
• Compact 1.5 inch overall length fits tight-clearance applications
• 1/2 inch drive compatible with standard impact wrenches and torque multipliers
• Lifetime warranty backed by the manufacturer

Compatibility

Designed as an OEM-specification impact socket for use with 1/2 inch drive impact wrenches and hand ratchets requiring a 5/8 inch 6-point hex socket.

Installation Notes

Always power down or de-energize equipment and relieve any stored pressure before loosening or torquing fasteners. Confirm the drive anvil on the impact wrench is clean and undamaged before seating the socket. Do not use impact sockets on hand-drive torque wrenches beyond their rated torque range, and inspect the socket for cracks or deformation before each use. Follow applicable workplace safety codes and manufacturer torque guidelines for the fastener being serviced.
