Emily ★★★★★

I needed some small fasteners for a jig I was building, and these fit perfectly with no fuss—the hex drive seated nicely and the thread engagement felt smooth. Really glad these come in a pack of 100 for the price.

Mia Y. ★★★★★

The black oxide finish on these #5-40 screws holds up beautifully—no rust or galling after multiple assembly cycles on my precision fixtures. The socket drive engages cleanly every time, and a full box of 100 for this size is a solid deal.

Elizabeth ★★★★★

I've used these in a few jig setups at work and they thread in clean every time, no galling or stripped heads. The alloy steel with the black oxide seems to hold up well in our oily machine shop environment.
