Proto J7328M Impact Socket 1/2 in Drive 28mm 6-point

Product Description

The PROTO J7328M is a 28mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and rattle guns. Built for heavy-duty fastener removal and installation, this socket features a hex drive configuration and measures 3.5 inches in overall length. The 6-point design maximizes contact with fastener flats, reducing the risk of rounding under high-torque impact conditions. At 1.2 pounds, it carries enough mass for durability without adding unnecessary weight to a tool bag. This is a professional-grade hand tool intended for mechanics, millwrights, and trade technicians working in industrial, automotive, and mechanical service environments.

This socket is suited for applications requiring a 1/2 inch drive in conjunction with a 28mm fastener size. Common use cases include heavy equipment service, commercial vehicle maintenance, structural assembly, and general mechanical repair where metric fasteners are standard. The 6-point geometry and impact-rated construction make it appropriate for both pneumatic and electric impact wrench use in shop and field settings.

Key Features

• 28mm socket size for metric fastener applications
• 1/2 inch drive compatible with standard impact wrenches
• 6-point hex drive design maximizes torque transfer and reduces fastener rounding
• 3.5 inches overall length provides reach in recessed fastener locations
• Impact-rated construction for use with pneumatic and electric impact tools

Compatibility

Designed as an OEM-style replacement or direct-fit addition for 1/2 inch drive impact socket sets requiring 28mm metric coverage.

Installation Notes

This socket is installed and removed by mechanics and trade technicians using 1/2 inch drive impact wrenches or breaker bars. Always confirm the fastener size before applying torque to avoid socket or fastener damage. Inspect the socket for cracks or wear before each use, and never use impact sockets with standard ratchets in high-torque applications. Follow applicable workplace safety guidelines when operating pneumatic or electric impact tools.
