Proto J6518H Impact Socket 1/4 in Drive 9/16 in 6-point

Product Description

The PROTO J6518H is a 6-point impact socket designed for use with 1/4 inch drive impact wrenches and rattle guns. It accepts a 9/16 inch fastener, features a hex drive configuration, and measures 2 inches overall length. The 6-point socket geometry concentrates force on the flat faces of a fastener rather than the corners, reducing the chance of rounding under high torque. At 0.15 pounds, it is a compact, lightweight socket suited to tight-access work in HVAC, plumbing, electrical, and general mechanical applications where a smaller drive size is practical.

This socket fits typical applications where a 1/4 inch drive impact tool is preferred over a larger drive for reduced bulk and maneuverability in confined spaces. It is commonly used by HVAC technicians, plumbers, electricians, and maintenance professionals working on panel covers, equipment housings, and light mechanical assemblies. The 9/16 inch size covers a range of fasteners found on residential and light commercial equipment.

Key Features

• 6-point contact geometry reduces fastener rounding under impact torque
• 1/4 inch drive fits compact impact wrenches and drivers commonly used in trade work
• 9/16 inch socket size for standard hex fasteners
• 2 inch overall length suits confined-space access
• Lightweight at 0.15 pounds for reduced tool fatigue

Compatibility

Designed for use with 1/4 inch drive impact wrenches, ratchets, and extension bars. Compatible with standard 1/4 inch square drive tooling.

Installation Notes

This socket is installed and removed by hand onto any 1/4 inch square drive impact tool. Ensure the socket is fully seated on the drive anvil before applying torque to prevent ejection under load. Impact sockets are rated for use with pneumatic or cordless impact wrenches and should not be substituted with chrome hand-tool sockets in impact applications. Inspect the socket for cracks or deformation before each use.
