Professional Applications & Engineering Value
This 316 stainless steel hex head screw delivers exceptional engineering value where corrosion resistance and mechanical strength are critical. The 1/4"-20 UNC coarse thread configuration prevents cross-threading during assembly while maintaining reliable performance in high-vibration environments. With 70,000 psi tensile strength and Rockwell B70 hardness, these partially threaded screws provide superior clamping force for structural applications, machinery assembly, and industrial equipment. The external hex drive accommodates standard tools for efficient installation in confined spaces. Ideal for marine equipment, chemical processing plants, and food processing machinery where corrosion resistance and regulatory compliance are mandatory.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with 1/4"-20 UNC coarse threading and 1-1/2" length. Fully compliant with ASME B18.2.1 dimensional standards, RoHS 3 (2015/863/EU) for hazardous substance restriction, and REACH (EC 1907/2006) regulations for chemical safety. The partially threaded design and external hex drive meet industrial fastening requirements for reliability and performance.
