Customer Reviews (4.6 / 5 · 5 reviews)

Zoe U. ★★★★★

I needed screws that could hold firm in a vibration-heavy jig setup, and the nylon pellet on these does exactly what it’s supposed to—keeps everything locked tight without backing out. The black oxide finish also resisted scuffs better than my usual zinc-plated ones.

Eva ★★★★★

Finally, a socket cap screw with a nylon pellet that actually stays put under vibration. The black oxide finish made them slide into my jig’s tapped holes without any binding.

Natalie ★★★★★

Put these 1-8 x 5" socket cap screws into a jig today, and the hex socket drive made installation smooth even in tight spots. The nylon pellet locking feature is a nice bonus for keeping them snug under vibration.
