High quality steel
You can feel the difference in quality compared to standard hardware store bolts. The heads do not strip easily.

Perfect for CNC projects
These screws are incredibly strong. I used them for mounting components on my CNC machine and they handled the vibration perfectly.

Good but tight fit
Great strength, but the threads were slightly tight on some pieces. Still usable with a tap.
Q: Can I use these for outdoor applications?

Q: Do you offer discounts for large orders?

Q: Are these screws made of stainless steel?
A: No, these are made of high-strength alloy steel with a black oxide finish.
