Proto J6516H Impact Socket 1/4 in Drive 1/2 in 6-point

Product Description

The PROTO J6516H is a 6-point hex drive impact socket designed for use with 1/4 inch drive impact wrenches and rattle guns. It accepts a 1/2 inch fastener and measures 2 inches in overall length, making it a compact option for tight-access fastening tasks. Built for impact tool use, it is engineered to handle the torsional stress and sudden shock loads that standard chrome sockets cannot reliably absorb. Weighing 0.12 pounds, it adds minimal bulk to a socket set. Technicians across mechanical, electrical, plumbing, and HVAC trades reach for impact sockets when driving or removing fasteners on equipment panels, flanges, and structural components.

This socket is suited for light-duty impact work where a 1/4 inch drive tool is the right size for the job. The 1/4 inch drive platform is common on cordless and pneumatic impact drivers used in residential service work, equipment installation, and panel assembly. The 6-point contact geometry distributes torque evenly across fastener flats, reducing the risk of rounding. It is appropriate for both residential and light commercial service applications where compact tooling is required.

Key Features

• 1/4 inch drive fits standard 1/4 inch impact wrenches and drivers
• 1/2 inch 6-point socket size for secure fastener engagement
• Hex drive style for direct hex fastener drive
• 2 inch overall length for use in moderate-clearance applications
• Lightweight at 0.12 pounds for easy handling in a socket set

Compatibility

Designed as an OEM-style replacement or supplemental socket for use with 1/4 inch drive impact wrenches and pneumatic or cordless impact drivers accepting standard 1/4 inch drive accessories.

Installation Notes

Install and remove with a 1/4 inch drive impact wrench or rattle gun only. Do not use impact sockets on non-impact ratchets for sustained torque applications, as the socket geometry differs from standard chrome sockets. Verify the fastener size and drive engagement before applying impact force to avoid fastener damage. Follow applicable safety guidelines when operating pneumatic or cordless impact tools.
