Customer Reviews (4.2 / 5 · 5 reviews)

Thomas ★★★★★

Used these for a jig I’m building and they threaded perfectly into tapped holes without any binding—the black oxide finish also gives them a solid, professional look.

Matthew ★★★★★

Was a bit skeptical about the nylon patch holding, but these screws thread in smooth and lock tight without any liquid threadlocker. Perfect for tooling jigs where vibration is a concern.

Kevin ★★★★☆

Bought these for a fixture build and the nylon patch is a nice touch—they hold their torque better than plain screws. The 12.9 hardness cuts clean threads in aluminum without stripping. Slight ding: the box arrived with a few rattling loose, but nothing damaged.
