316 Stainless Steel Square Nuts Supper Corrosion Resistant M3 M6 M8 Square Nut Bolt

Açıklama

A square nut is a type of four-sided nut with a square shape instead of the traditional hexagonal design. It provides a larger bearing surface , reducing the risk of loosening under vibration and offering better grip when used with a wrench or pliers. Square nuts are commonly used in woodworking, construction, and machinery where a flat surface contact is preferred.

Materials

Carbon Steel (Grade 4.8, 8.8, 10.9) – High strength, commonly zinc-plated for corrosion resistance.
Stainless Steel (SS304, SS316) – Excellent corrosion resistance, ideal for marine and outdoor use.
Brass – Good electrical conductivity, used in plumbing and decorative applications.
Aluminum – Lightweight, suitable for aerospace and electronics.
Nylon/Plastic – Non-conductive, used in food processing and medical devices.

Applications

Woodworking & Furniture – Used with carriage bolts for secure fastening in wooden structures.
Construction & Framing – Provides a flat surface for bolted connections in steel structures.
Automotive & Machinery – Prevents loosening in high-vibration environments.
Marine & Outdoor Equipment – Stainless steel square nuts resist saltwater corrosion.
Electrical & Electronics – Brass square nuts used in grounding applications.
DIY & Repair Work – Easy to grip and install without specialized tools.
Excellent Use Case: Square Nuts in Wooden Furniture Assembly

Why?

Larger surface area prevents sinking into wood.
Stays secure even with wood expansion/contraction.
Easy to tighten with a wrench or pliers.

Example:

IKEA furniture often uses M6 or M8 square nuts with carriage bolts for bed frames and shelving.
Load Tested: Up to 500N clamping force in wooden joints.

Conclusion

Square nuts are durable, vibration-resistant fasteners ideal for woodworking, construction, and machinery . Their flat design, material options, and surface treatments make them suitable for high-stress, outdoor, and electrical applications .
