Stainless Steel Long Nuts Factory China Professional Suppliers of 304 and 201 Round Elongated Nuts
Stainless Steel Long Nuts Factory China Professional Suppliers of 304 and 201 Round Elongated Nuts
Our premium Stainless Steel Long Nuts, also known as round elongated nuts, are engineered for high-performance fastening where extended thread engagement is critical. Available in high-grade 304 and 201 stainless steel, these fasteners provide a robust solution for increasing connection strength and preventing loosening in demanding industrial environments.
Whether you are securing heavy machinery or implementing structural fixings, our long nuts offer a superior alternative to standard nuts by providing 2 to 4 times the threading length. This ensures maximum stability and security, making them an essential component for professional engineering and construction projects worldwide.

Frequently Asked Questions
304 stainless steel has higher nickel and chromium content, offering superior corrosion resistance for outdoor and coastal use, whereas 201 is a more cost-effective option suited for dry, indoor applications.
Long nuts provide a significantly larger thread engagement area, which increases the overall connection strength and reduces the likelihood of the fastener loosening under vibration.
Yes, we supply both Metric (e.g., M6-M20) and Imperial (e.g., 1/4"-1/2") specifications. Please ensure you select the exact diameter and pitch to match your bolts.
It is not recommended. Due to higher manganese content, 201 stainless steel is prone to rust in high-salinity or humid coastal environments. We strongly suggest 304 grade for such scenarios.
The length should be based on the required thread engagement for your specific design. Generally, the longer the engagement, the higher the stability and anti-loosing capability.
Yes, we are a professional bulk supplier of cutting tool and fastener accessories, offering highly competitive pricing for large-scale industrial orders.
