Proto J7336 Impact Socket 1/2 in Drive 1-1/8 in 12-point

Product Description

The PROTO J7336 is a 12-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. It accepts a 1-1/8 inch fastener and measures 3.5 inches overall length, giving technicians adequate depth clearance in tight installation spaces. Built for high-torque applications, this socket is a standard tool for mechanics, HVAC technicians, plumbers, and electricians working on equipment fasteners, flanges, and mechanical assemblies. At 1.06 pounds, it carries enough mass to support impact-rated use without adding unnecessary weight to a tool bag or service cart.

The J7336 is suited for residential and commercial service work where 1/2 inch drive impact tools are standard. Common applications include equipment mounting hardware, structural fasteners on HVAC units, pump flanges, and panel work where a 1-1/8 inch fastener is present. The 3.5 inch overall length provides reach in recessed fastener locations without requiring an extension in most standard service scenarios. This socket is appropriate for shop use and field service alike.

Key Features

• 12-point socket design engages fasteners at more contact positions, reducing rounding on worn hardware
• 1/2 inch drive fits standard impact wrenches and ratchets used across HVAC, plumbing, and mechanical trades
• 3.5 inch overall length provides reach for recessed or partially obstructed fastener locations
• 1.06 pound weight reflects impact-grade construction suitable for high-torque applications

Compatibility

Designed as a standard 1/2 inch drive impact socket compatible with 1/2 inch drive impact wrenches, ratchets, and torque wrenches used in mechanical, HVAC, plumbing, and electrical service applications.

Installation Notes

This socket is installed and removed by hand onto a 1/2 inch drive tool — no additional tools required for attachment. Always confirm the socket is fully seated on the drive before applying torque. When using with a powered impact wrench, ensure the fastener size matches the 1-1/8 inch socket to avoid rounding. Follow applicable workplace safety guidelines when operating impact tools.
