Zoe I. ★★★★★

Used about 40 of these for a jig build, and every single one threaded in smoothly without any binding. The flat head sits flush perfectly, and the zinc coating looks durable. Solid value for the quantity you get.

George W. ★★★★★

The hex drive seated perfectly without stripping even under torque, and the zinc plating on these M6-1 x 20mm screws looks like it’ll hold up well in my shop. Exactly what I needed for securing a tooling fixture.

Violet P. ★★★★★

I needed these for a jig I was building, and the Class 10.9 alloy steel feels incredibly durable compared to cheaper screws. They threaded smoothly into every hole without any binding.
