Customer Reviews (4.6 / 5 · 5 reviews)

Timothy ★★★★★

Needed a solid fastener for a precision jig I was machining, and the black oxide finish on these #0-80 screws adds just enough grip without galling. All 1,000 arrived neatly packed and threaded perfectly into the tapped holes first try.

Julian ★★★★★

Had to replace some tiny fasteners on a hobby CNC jig, and these #0-80 screws fit perfectly with no stripped heads from the hex drive. Black oxide finish looks nice and I was glad to get a full thousand count for the price.

Evelyn O. ★★★★★

Finally, a bag of screws where the threads are actually clean and consistent. The black oxide finish on these #0-80s held up great while I was fitting them into a jig.
