I was pleasantly surprised by how smoothly these black oxide screws threaded into my tooling jig—the nylon pellet really holds them tight without galling. The hex drive made installation straightforward, and the 25-pack gives plenty for future projects.

These flat head hex screws seated perfectly flush in my jig, which was exactly what I needed. The nylon pellet keeps them locked in place even after multiple adjustments.

I needed a bolt that could handle constant vibration on a jig, and these alloy steel screws with the nylon pellet have held fast through three weeks of heavy use. The black oxide finish also resists shop grime better than I expected.
