- Durable Rockwell B87 hardness maintains structural integrity through repeated use and vibration
- Broad compatibility with UNC coarse threading (3/8"-16) for standard industrial applications
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these rounded truss head screws deliver exceptional performance where vibration resistance and surface marring prevention are critical. The 18-8 stainless steel composition provides inherent corrosion resistance, eliminating premature failure in moisture-exposed applications. The unique drilled spanner drive offers tamper-resistant security while the wide truss head profile distributes clamping force over a larger area, preventing damage to softer materials. With coarse UNC threading and full threading along the 1" length, these screws ensure rapid installation and reliable holding power in machinery, electrical enclosures, and structural assemblies where ASME B18.6.3 compliance is mandatory.
Specification Summary & Compliance
This 3/8"-16 UNC screw features precise Class 2A thread fit tolerances with coarse thread spacing, manufactured to exacting ASME B18.6.3 specifications. The fastener maintains full regulatory compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across various industrial sectors. Mechanical properties include consistent 70,000 psi tensile strength and Rockwell B87 hardness verification for quality assurance.
