Full spectrum of industrial fastening solutions | Covering both standard and custom parts
Our stainless steel metric square nuts are designed for secure fastening in machinery equipment, industrial assembly, repair work, furniture hardware, construction hardware, and general fastening applications. The product features a four-sided square shape with internal metric threads, providing a practical fastening solution for applications where square nuts are preferred over standard hex nuts.
Made from stainless steel 304 or stainless steel 316, these square nuts provide a clean silver metallic appearance and are suitable for buyers who require stainless steel fastening components. The product has a plain stainless steel finish, without zinc plating or galvanized coating.
The square shape provides flat contact surfaces and can be useful in slots, channels, fixtures, and special assembly structures where the nut needs better positioning or limited rotation during installation.

Square nuts are often used where the nut needs to stay in position inside a slot, channel, or fixture. The four-sided shape helps provide stable contact with surrounding structures during fastening.
For buyers who need stainless steel nuts instead of carbon steel coated nuts, 304 and 316 stainless steel options help match different project and application requirements.
The metric thread design allows the nut to be used with compatible metric bolts, screws, and threaded rods, reducing thread mismatch during procurement.
Square nuts can be applied in machinery repair, equipment assembly, furniture hardware, and industrial maintenance where a standard hex nut may not be the best fit.
