Overview

This stainless steel hex flange nut is engineered for demanding fastening applications where corrosion resistance, strength, and a secure, vibration-resistant joint are required. Manufactured from grade 304 stainless steel, it meets the A2-70 property class, ensuring a reliable combination of durability and mechanical performance. The integrated, non-serrated flange eliminates the need for a separate washer by distributing clamping force over a wider surface area. This design helps prevent damage to the connected material and improves joint stability. The plain finish makes it suitable for a broad range of general industrial, construction, and maintenance environments.
