Professional Applications & Engineering Value

This 8-36 UNF fine thread cap nut is engineered to address critical challenges in industrial assembly, where vibration resistance and thread integrity are paramount. The zinc-plated steel material provides a durable barrier against corrosion, significantly increasing the component's lifespan in harsh conditions. The Class 2B thread fit and fine thread spacing work in tandem to deliver a secure, vibration-resistant connection that is less prone to loosening under dynamic loads, making it ideal for precision equipment, automotive subsystems, and machinery. The external hex drive design facilitates quick and secure installation with common tools, streamlining production and maintenance processes. This nut is a reliable solution for applications demanding a sealed end, thread protection, and a high-strength, RoHS compliant fastener.

Specification Summary & Compliance

This cap nut adheres to the UNF (Unified National Fine) thread standard with a size of 8-36 and a Class 2B thread fit for consistent dimensional accuracy and assembly performance. The manufacturing complies with standard industrial practices for inch-system fasteners. It is confirmed to be RoHS 3 (2015/863/EU) compliant under exemption 6(a)-I for lead as an alloying element in steel, ensuring its suitability for use in products marketed within the EU and other regions with similar environmental regulations.
