Professional Applications & Engineering Value
This black-oxide stainless steel pan head screw is engineered to address common industrial challenges such as corrosion, high-stress fatigue, and assembly efficiency. The 18-8 stainless steel base material, enhanced by a black-oxide coating, provides exceptional resistance to rust and chemical exposure, making it suitable for outdoor equipment, electrical enclosures, and machinery in humid or corrosive settings. The coarse UNC 6-32 thread and Class 2A fit ensure quick, secure fastening with standard tools, reducing installation time and minimizing thread damage. With a 70,000 psi tensile strength and fully threaded shank, it delivers uniform clamping force and vibration resistance in automotive, aerospace, and electronics assemblies, supporting long-term reliability and reduced maintenance costs.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent assembly tolerance and UNC coarse threading (6-32 size) per industry norms. Manufacturing and quality are governed by ASME B18.6.3 specifications, ensuring uniformity and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting environmentally responsible procurement.
