Customer Reviews (4.2 / 5 · 5 reviews)

Hannah ★★★★★

These 5-inch screws threaded perfectly into my jig without any binding. The hex socket drive gripped the driver bit firmly, making assembly much smoother than I expected from bulk fasteners.

Ava ★★★★☆

The black oxide finish looks even better in person than in photos, and the threading on all fifty pieces stayed clean through my entire project. Only knocked off a star because a few screws had slightly tight fittings that needed a bit more torque than expected.

Hazel ★★★★☆

Used a few of these for a press jig and the hex drive seated perfectly without stripping. The black oxide finish has held up well after a week of use, though I wish the package came with a few extras for the price.
