Professional Applications & Engineering Value
This 316 Stainless Steel Pan Head Phillips Screw is engineered to solve critical challenges in demanding industrial settings. Its passivated finish significantly enhances the natural corrosion resistance of 316 stainless steel, making it an ideal choice for applications exposed to chemicals, saltwater, and high humidity, such as marine equipment, chemical processing plants, and food machinery. The combination of 80,000 psi tensile strength and a Rockwell B85 hardness ensures the fastener can withstand vibrational forces and heavy loads without shearing or deforming. The 1/4"-20 UNC coarse thread and fully threaded design allow for faster installation and superior grip in softer materials or where rapid assembly is required, reducing labor time and improving project efficiency in manufacturing, construction, and OEM applications.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC thread with a Class 2A fit for consistent dimensional accuracy and reliable assembly. Manufacturing and dimensional specifications conform to ASME B18.6.3. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated industrial and international markets.
