Customer Reviews (4.8 / 5 · 5 reviews)

Adam ★★★★★

Exactly what I needed to join two 5/8" rods for my project. The set screws threaded in smoothly and held tight without any wobble once I tightened them down.

Stella ★★★★★

The set screws grip the shaft firmly, and the smooth female ends made aligning my two pieces dead simple. No wobble at all once tightened down, exactly what I needed for a quick repair.

Joshua J. ★★★★★

Used it to join two short shafts for a custom project, and the threads were perfectly smooth on both ends. The set screws tightened down evenly without stripping, which made installation quick.
