Proto J7428S Impact Socket 1/2 in Drive 7/8 in 8 Point

Product Description

The PROTO J7428S is an 8-point impact socket designed for heavy-duty fastening and removal applications. Built for 1/2 inch drive impact wrenches, it fits 7/8 inch fasteners and measures 1.625 inches overall length. The 8-point geometry engages fasteners at more contact points than a standard 6-point, making it suited for use on square-drive and double-square fastener heads common in industrial and fleet maintenance environments. At 0.48 pounds, it is a compact, single-piece socket intended for professional tool kits.

This socket is used by mechanics, maintenance technicians, and industrial tradespeople who work with 1/2 inch drive impact tools. The 8-point configuration sees common use in heavy equipment maintenance, fleet repair, and manufacturing facilities where square-head or 12-point fasteners require a dedicated socket. Its short overall length of 1.625 inches makes it practical in space-constrained fastener locations.

Key Features

• 1/2 inch drive compatible with standard impact wrenches and ratchets
• 7/8 inch socket size for matching fastener heads
• 8-point design for engagement on square and double-square fasteners
• 1.625 inch overall length for use in tighter clearance areas
• Rated for impact tool use, suitable for high-torque applications

Compatibility

Designed as an OEM-style replacement or direct-fit socket for 1/2 inch drive impact wrenches and ratchets requiring a 7/8 inch, 8-point socket.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench or ratchet. Ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Inspect the socket for cracks or deformation before each use, and do not use damaged sockets under impact loads. Follow applicable workplace safety standards when operating impact tools.
