Customer Reviews (4.8 / 5 · 5 reviews)

Avery ★★★★★

I needed some non-conductive fasteners for a custom jig setup, and these 2000-count nylon screws are perfect. The #4-40 thread cuts cleanly into the plastic without cracking, and the hex drive lets me torque them precisely without stripping.

Adam N. ★★★★★

Finally found nylon screws that won't strip or corrode in my jig setup, and the 2000-count package will last me years. The hex socket drive bites perfectly with a standard hex key.

Zoe ★★★★★

The hex socket drive makes these easy to tighten in tight spots, and I'm pleasantly surprised how uniform the threads are across the whole pack. Exactly what I needed for a small jig project.
