Professional Applications & Engineering Value

This 316 stainless steel hex head screw delivers critical engineering advantages in demanding industrial environments where corrosion resistance and structural integrity are paramount. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures reliable performance in heavy machinery, structural steel connections, and marine applications where vibration and dynamic loads are common. The 1 1/2"-6 UNC coarse threading with Class 2A fit provides excellent engagement in both metals and plastics, reducing cross-threading risks while maintaining secure fastening. The external hex drive with substantial head dimensions enables high-torque installation without stripping, making it ideal for maintenance operations and production line assembly where speed and reliability are essential. The partial threading design allows for precise unthreaded shank sections to bear against materials, preventing loosening under shear forces commonly encountered in construction and heavy equipment applications.

Specification Summary & Compliance

This industrial fastener maintains precise dimensional standards with Class 2A thread fit tolerance and UNC coarse thread specifications ensuring proper engagement and interchangeability. Manufacturing complies with ASME B18.2.1 standards for hex head screws, guaranteeing consistent quality and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for use in sensitive applications. The inch system measurements provide compatibility with North American industrial specifications and replacement part requirements.
