Proto J74284P 1/2 in Drive 1-1/16 in Impact Socket

Product Description

The PROTO J74284P is a 6-point hex drive impact socket built for heavy-duty fastening applications. It accepts a 1/2 inch drive and fits 1-1/16 inch fasteners, with an overall length of 3 inches. Constructed from alloy steel, it is engineered to withstand the high-torque output of pneumatic and electric impact wrenches without cracking or rounding under load. This socket meets ASME B107.2 standards, confirming dimensional and performance compliance. It is a direct-use tool for licensed trades and experienced technicians who need reliable, impact-rated hand tools on the job.

This impact socket is suited for residential and commercial mechanical work, including HVAC equipment installation, plumbing rough-in, electrical panel mounting, and general mechanical fastening tasks. The 6-point drive geometry maximizes contact with fastener flats, reducing the risk of slippage on stubborn or corroded hardware. At 3 inches overall length, it fits standard impact driver configurations without clearance issues in most service environments.

Key Features

• 1/2 inch drive size compatible with standard impact wrenches and ratchets
• 1-1/16 inch socket size for common heavy fastener applications
• 6-point hex drive geometry for maximum torque transfer and reduced fastener rounding
• Alloy steel construction rated for impact tool use
• Meets ASME B107.2 dimensional and performance specification
• 3 inch overall length for versatile clearance in standard service scenarios

Compatibility

Designed as an impact-rated replacement or addition for 1/2 inch drive socket sets used with pneumatic, cordless, or corded impact wrenches in trade and industrial service applications.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench or breaker bar rated for impact use. Always ensure the socket is fully seated on the fastener before applying torque. Do not use impact sockets with non-impact hand ratchets as the primary drive tool for sustained high-torque work, as this can damage the drive mechanism. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
