George ★★★★★

These are holding my jig fixtures together with zero give—the nylon patch is a godsend when you need them to stay put under vibration. The partially threaded length gives me just the right grip for clamping plates that aren't perfectly parallel. Surprisingly clean threading for the price, no burs to

Andrew ★★★★★

The black oxide finish on these screws is darker and more consistent than I expected, which helps them blend in on my tooling setup. They threaded easily into a steel fixture plate, and the nylon patch held firm without any loosening during use.

Edward V. ★★★★☆

Used a few of these to secure a jig on the mill table, and the nylon patch on the threads held tight without needing a separate lock washer. They seat nicely with a hex key and the black oxide finish looks clean, though I wish they came with a few extras for the price.
