Solid industrial grade

Needed M24 specifically for a large frame assembly. Quality is good, though shipping took a few extra days.

Excellent corrosion resistance

Used these for a boat fitting project and they held up perfectly against saltwater exposure. The 316 grade is genuine.

Good fit but tight slots

The screw quality is high and threads are clean. The slot was a bit tight for my screwdriver but manageable.

Great for machinery

Needed headless screws for a conveyor belt adjustment. These hold vibration well and do not strip easily.
