Customer Reviews (4.4 / 5 · 5 reviews)

Eva ★★★★★

Used these on a jig fixture where I needed to lock an adjustment rod without marring it — the nylon pellet works perfectly for that. The hex socket let me get them snug in a tight spot without stripping.

Leo ★★★★★

I needed something that wouldn't mar the shaft surface, and the nylon pellet in these set screws does exactly that. They tightened down securely with a hex key and held fast under vibration in my jig setup.

Eva ★★★★☆

The nylon pellet holds tight without stripping the threads, which is exactly what I needed for a repeated adjustment setup. They’re a bit pricier than standard set screws, but the hex socket drive makes them easy to torque in cramped spots.
