Proto J7412MT Impact Socket 1/2 in Drive 12mm

Product Description

The PROTO J7412MT is a 12mm impact socket designed for 1/2 inch drive impact wrenches and rattle guns used in heavy-duty fastening applications. Built to a 12-point configuration, it seats on hex fasteners at multiple angles, reducing setup time in tight spaces. The overall length measures 1.5 inches, making it a compact option for standard-reach applications. This socket is intended for professional tradespeople, mechanics, and service technicians who run 1/2 inch drive impact tools in the field or in the shop. Its weight of 0.18 pounds keeps the tool assembly light without sacrificing drive engagement.

This socket fits common 1/2 inch drive impact wrenches and is suited for automotive, HVAC equipment service, mechanical assembly, and general maintenance tasks where a 12mm fastener is encountered. It is appropriate for both shop environments and field service calls where compact tooling is needed. The 12-point geometry allows engagement in confined areas where a standard 6-point socket may not align quickly.

Key Features

• 1/2 inch drive compatible with standard impact wrenches and breaker bars
• 12mm socket size for metric fastener applications
• 12-point design allows multiple engagement positions on hex fasteners
• Compact 1.5 inch overall length suits standard-reach service tasks
• Lightweight at 0.18 pounds for reduced fatigue during extended use

Compatibility

Designed as an OEM-style replacement and standard fitment socket for 1/2 inch drive impact tools used in metric fastener applications.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench, torque wrench, or breaker bar. Ensure the socket is fully seated on the fastener before applying drive force to prevent rounding. Inspect the socket for cracks or wear before each use, particularly after high-torque impact cycles. No power disconnection is required for hand-tool use, but follow applicable lockout/tagout procedures when servicing powered equipment.
