Customer Reviews (4.8 / 5 · 5 reviews)

Ryan ★★★★★

Had to replace some worn bolts on a jig fixture, and the nylon patch on these screws held tight without any need for thread locker. The black oxide finish gives them a professional look, too.

Mia S. ★★★★★

Picked up a pack for a precision assembly project, and the nylon patch is a nice touch—holds the threads without any extra goop. The black oxide finish looks clean and professional against the steel.

Kevin ★★★★★

Used a handful of these to secure a jig base to the milling table and the black oxide finish seems tough enough to shrug off light coolant splashes. The hex socket drive made installation a breeze in a tight spot where a wrench wouldn't fit.
