Details

Tekton impact universal joints are for use with impact tools

Access at an Angle

Attach a universal joint to your impact tool to reach around obstructions and access fasteners at an angle.
The universal joint has a 30 degree working angle

30-Degree Working Angle

The joint rotates smoothly and continuously at up to a 30-degree angle.

6-Sided Pinless Joint

Our ball-and socket-style joint is stronger than joints that use pins. The 6-sided ball operates more smoothly than 4-lug designs.

Parts and Assembly

The universal joint comes pre-lubricated with SuperLube Multi-Purpose Synthetic Grease (NLGI 2) with Syncolon® (PTFE). Maintain the lubrication using this grease or a comparable grease as needed to reduce wear over time.

Drive Tool Retention

The universal joint works with both types of anvils found on 1/2 inch drive impact wrenches:
