What is the difference between A2 and A4 stainless steel bolts?

A2 (304) is ideal for standard outdoor and industrial use, while A4 (316) contains molybdenum, offering higher corrosion resistance for marine, chemical, and salt-spray environments.

Do you provide matched nut & bolt or nut & washer kits?

Yes. We can supply pre-packed sets or assembly kits customized for distributors or hardware chains.
