Professional Applications & Engineering Value
Engineered for demanding industrial settings, these black-oxide alloy steel socket head cap screws deliver robust performance where reliability is critical. The Class 3A coarse UNRC threads ensure tight, secure fits in machinery, automotive assemblies, and heavy equipment, resisting loosening under vibration. With a 170,000 psi tensile strength and Rockwell C37 hardness, they withstand extreme loads and abrasion, making them ideal for high-stress applications like aerospace, construction, and manufacturing. The black-oxide surface treatment enhances corrosion resistance, extending lifespan in humid or corrosive environments, while the hex drive facilitates efficient installation with standard tools, reducing downtime.
Specification Summary & Compliance
This product adheres to precise dimensional standards, including Class 3A thread fit for accuracy and UNRC coarse threads per inch specifications. It meets ASTM A574 for material and manufacturing quality, ensuring consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms environmental safety, free from hazardous substances, supporting sustainable industrial practices.
