Professional Applications & Engineering Value
This 316 Stainless Steel Pan Head Phillips Screw is engineered to solve critical challenges in demanding industrial environments. Its passivated finish significantly enhances the innate corrosion resistance of 316 stainless steel, making it ideal for applications exposed to moisture, chemicals, and salt spray, such as marine hardware, food processing equipment, and outdoor structures. The combination of 80,000 psi tensile strength and a fully threaded UNC coarse thread provides superior vibration resistance and clamp load retention, preventing loosening in high-stress assemblies. The pan head with a No. 3 Phillips drive offers a low-profile, secure fastening solution that is easy to install with common tools, streamlining production and maintenance workflows while ensuring long-term reliability.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC thread with a Class 2A fit for precise dimensional accuracy. It is manufactured in compliance with the ASME B18.6.3 standard, ensuring consistent quality and interchangeability. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial components.
