Professional Applications & Engineering Value
These passivated 18-8 stainless steel rounded truss head screws deliver exceptional engineering value across industrial applications where corrosion resistance and structural integrity are paramount. The wide truss head design provides superior bearing surface distribution, effectively reducing the risk of material damage in softer substrates while maintaining clamp load. With UNC coarse threading and Class 2A thread fit, these fasteners ensure reliable installation in various materials without cross-threading concerns. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes these 8-32 x 2" screws ideal for heavy-duty assemblies, electrical enclosures, machinery guards, and structural frameworks where vibration resistance and long-term performance are critical requirements.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent performance. Features UNC coarse threading (8-32 thread size) with right-hand thread direction and fully threaded 2" length. Complies with ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. Meets environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) requirements, ensuring suitability for global industrial applications with strict material restrictions.
