  • Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in regulated industries and global markets.

Professional Applications & Engineering Value

This 1/4-20 hex head screw is engineered for industrial applications where corrosion resistance and high tensile strength are non-negotiable. Manufactured from 18-8 Stainless Steel, it effectively combats rust and chemical degradation in demanding environments such as marine, chemical processing, and outdoor construction. The coarse UNC thread and Class 2A fit provide excellent engagement in a variety of materials, reducing the risk of cross-threading and ensuring a reliable, vibration-resistant connection. The combination of 80,000 PSI tensile strength and a fully threaded 10-inch length makes it an ideal heavy-duty fastener for structural frameworks, machinery assembly, and other critical joints that require long-term integrity and maximum load-bearing capacity.

Specification Summary & Compliance

This fastener meets precise dimensional standards with a 1/4"-20 UNC coarse thread and a Class 2A thread fit for consistent, reliable assembly. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and approved for use in sensitive and regulated industrial applications.
