Proto J66170P Impact Universal Joint 1/4 in Male Female

Product Description

The PROTO J66170P is an impact-rated universal joint designed for use with 1/4 inch drive tools in demanding fastening and removal applications. It features a 1/4 inch male drive end and a 1/4 inch female drive end, with an overall length of 1-13/32 inches. Built to handle the high-torque, high-vibration output of pneumatic and cordless impact drivers, this joint allows angular movement between a drive tool and socket in tight or awkward access points. It meets ASME B107.2 specification, confirming it is manufactured to recognized hand tool performance standards. Technicians in HVAC, plumbing, electrical, and general mechanical trades rely on impact-rated universal joints for repetitive fastening tasks where a direct-drive approach is not possible.

This universal joint is suited for residential and light commercial service work where 1/4 inch drive impact tools are standard. Common applications include equipment panel fastener removal, sheet metal screw driving in HVAC installations, electrical box work, and any confined-space fastening scenario requiring an angled drive path. The compact 1-13/32 inch overall length keeps the tool profile short, making it practical in tight mechanical spaces.

Key Features

• Impact-rated construction handles high-torque and high-vibration drive tools
• 1/4 inch male to 1/4 inch female drive configuration for standard 1/4 inch drive impact sockets and bits
• Overall length of 1-13/32 inches keeps tool stack short in confined spaces
• Meets ASME B107.2 specification for hand tool performance
• Allows angular drive path between impact tool and socket in restricted access areas

Compatibility

Designed as an OEM-style replacement and aftermarket option for 1/4 inch drive impact tool sets requiring a universal joint adapter.

Installation Notes

This joint is intended for use by trade professionals working with 1/4 inch drive impact drivers, ratchets, or extension sets. Ensure the drive tool is fully powered down or depressurized before connecting or disconnecting the universal joint. Inspect the joint for wear or play before each use, as impact service accelerates wear compared to hand-ratchet use. Replace immediately if looseness or cracking is detected, as a failed universal joint under impact load can cause injury or fastener damage.
