Proto J7418MT Impact Socket 1/2 in Drive 18mm 12-point

Product Description

The PROTO J7418MT is a 12-point impact socket designed for use with 1/2 inch drive impact wrenches and rattle guns. Built for professional fastener work, it accepts an 18mm fastener and has an overall length of 1.5 inches, making it a compact option for confined spaces and standard mechanical applications. The 12-point geometry allows engagement at multiple angles, reducing the need to reposition the socket in tight quarters. Weighing 0.18 pounds, this socket is suited for daily use by mechanics, industrial technicians, and maintenance trades who rely on impact-rated tooling for consistent torque delivery.

This socket is appropriate for automotive, fleet, industrial, and general mechanical applications where an 18mm fastener is driven using a 1/2 inch drive impact tool. The 12-point configuration is commonly used in production environments and field service where quick socket placement and engagement speed matter. It fits standard 1/2 inch drive impact wrenches and torque wrenches used across automotive and heavy equipment service.

Key Features

• 1/2 inch drive size compatible with standard impact wrenches and torque wrenches
• 18mm socket size for metric fastener applications
• 12-point design allows multiple engagement positions for faster setup
• Compact 1.5 inch overall length suits tight access areas
• Impact-rated construction for use with pneumatic and electric impact tools

Compatibility

Designed as an OEM-style replacement or direct-use impact socket for 1/2 inch drive impact tools requiring an 18mm metric socket.

Installation Notes

Installation and use of impact sockets should be performed by qualified mechanics or trades personnel familiar with impact tooling. Always verify the socket is fully seated on the drive anvil before applying torque. Do not use impact sockets with standard hand-turn ratchets beyond their rated torque range, and inspect the socket for cracks or wear before each use. Follow applicable workplace safety standards when operating pneumatic or electric impact tools.
