Description
The Stainless Steel Flange Nut is an all-in-one fastener featuring a hexagonal body with a built-in, non-spinning washer (flange) at its base.This unique design distributes load evenly, enhances stability, and prevents loosening under vibration or heavy loads. Manufactured from premium 304 stainless steel or 316 stainless steel, these flange nuts provide outstanding corrosion resistance, durability, and long-lasting performance. With their deep, precise threads and standard hexagonal design, Stainless Steel Flange Nuts are widely used in automotive, construction, marine, and industrial applications where secure fastening and resistance to rust are essential.
Features & Benefits
- Enhanced Load Distribution: The integrated flange provides a larger bearing surface, which distributes the fastening force more evenly across the material. This reduces the risk of loosening and damage to the fastened part.
- Corrosion Resistance: Made from either 304 or 316 stainless steel, this nut offers excellent resistance to wear, rust, and oxidation, particularly in humid or harsh environments like marine and chemical settings.
- Secure Locking: The flange, often featuring serrations on its underside, provides a locking action that prevents the nut from backing off under vibration. This ensures a secure and firm connection.
- Streamlined Assembly: By combining the nut and washer into a single component, this product simplifies assembly and reduces part inventory, saving time and effort during installation.
