Customer Reviews (4.2 / 5 · 5 reviews)

Henry Q. ★★★★★

Was putting together a new fixture for a production run and these M4s threaded in cleanly without any binding. The black oxide finish looks consistent across all 600 pieces.

Hannah J. ★★★★★

The hex socket drive seated perfectly on my driver with zero stripping, even when I torqued them into a steel jig. The black oxide finish gives them a clean, uniform look and they feel solidly machined for the price, especially at 600 pieces per pack.

Hazel ★★★★★

I needed a batch of M4 screws for a custom jig, and these black oxide ones have a nice, even finish without any burs. The hex drive seated perfectly with my Allen key, and they threaded smoothly into tapped holes. Solid quality for the price, especially in a bulk pack like this.
