Customer Reviews (4.8 / 5 · 5 reviews)

Isabella T. ★★★★★

These are perfect for jigs and fixtures where you need a clean, flush finish. The hex drive grips firmly and the zinc coating looks consistent across all 600 pieces.

Hannah ★★★★★

I needed a bulk supply of M3 screws for jig assembly, and these 16mm flat heads are consistently clean and thread smoothly. The zinc plating gives them a nice finish that resists rust in my shop. A solid batch at this price point.

Natalie ★★★★★

I needed a big batch of M3 screws for a CNC fixture project, and these 16mm ones came fully threaded with a nice zinc coating. They threaded into tapped holes smoothly without binding, and the hex drive held up to torquing. Solid value for 600 pieces.
