Professional Applications & Engineering Value

These passivated 18-8 stainless steel rounded truss head screws deliver critical performance 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 under vibration and load stress, while the wide truss head profile distributes clamping force effectively across softer materials without surface damage. The UNC coarse threading with Class 2A fit provides excellent engagement in metals, plastics, and composite materials, making these partially threaded screws ideal for assembly lines, machinery fabrication, and structural applications where precise thread length control is essential. The Phillips No. 2 drive system enables efficient installation with standard tools, reducing assembly time in high-volume production environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit and UNC thread form ensuring consistent performance across applications. These rounded truss head screws comply with ASME B18.6.3 mechanical specifications and maintain compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 10-24 thread size with coarse thread spacing and 5-inch overall length provides reliable fastening solutions for industrial equipment, manufacturing assemblies, and construction applications requiring durable, corrosion-resistant fasteners.
