Frequently Asked Questions

Q: What sizes are these stainless steel knurled nuts available in?

A: These knurled hand nuts are available in M3, M4, M5, M6, M8, M10, and M12 metric thread sizes, making them compatible with a broad range of bolts and applications from small DIY assemblies to larger mechanical projects.

Q: What is the difference between the through-hole and blind-hole configurations?

A: A through-hole knurled nut has an opening that runs completely through the nut, allowing the bolt to pass all the way through. A blind-hole nut has a closed bottom, which provides a cleaner finish on one side — ideal for applications where the end of the bolt should not be exposed.

A: Yes! The distinctive knurled outer surface is specifically designed for tool-free hand tightening. The textured grip pattern ensures a firm, slip-resistant hold so you can quickly fasten or loosen the nuts by hand during assembly or adjustments.

Q: Are these nuts suitable for outdoor or high-moisture environments?

A: These nuts are made from 304 stainless steel, which offers strong corrosion and oxidation resistance, making them well-suited for applications exposed to moisture or varying weather conditions.
