Proto J07518S Impact Socket 3/4 in Drive 1-1/8 in 8-pt

Product Description

The PROTO J07518S is an 8-point impact socket designed for heavy-duty fastener work in industrial and mechanical service applications. Built for 3/4 inch drive impact wrenches, this socket measures 1-1/8 inches across and has an overall length of 2-1/4 inches. The 8-point geometry engages square and 12-point fasteners while distributing torque more evenly across the fastener faces, reducing rounding under high-impact loads. Weighing 1.42 pounds, the socket is sized for demanding hand-tool work where a standard chrome socket would not hold up to repeated impact use. Mechanics, millwrights, and heavy equipment technicians are the typical end users for this drive and size range.

This socket fits into maintenance, repair, and overhaul workflows where 3/4 inch drive impact tooling is standard. The 1-1/8 inch size appears frequently in structural fastener applications, industrial machinery, agricultural equipment, and heavy truck service. The 2-1/4 inch overall length suits most standard access situations without requiring an extension in typical flange and fastener configurations.

Key Features

• 3/4 inch drive fits standard 3/4 inch drive impact wrenches and ratchets
• 8-point design engages square-head and worn 12-point fasteners with reduced slippage
• 1-1/8 inch socket size covers a common structural and heavy equipment fastener range
• 2-1/4 inch overall length provides a compact profile for general-access work
• Impact-rated construction handles repeated high-torque use from pneumatic or electric impact tools

Compatibility

Designed as an OEM-style impact socket for use with 3/4 inch drive impact wrenches, torque multipliers, and breaker bars in industrial and heavy-duty service applications.

Installation Notes

Always confirm the drive tool is rated for impact use before attaching this socket. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Never use impact sockets with standard chrome drive tools, as the torque and shock loads can cause failure. Ensure the retaining pin or hog ring is fully seated before applying load.
