Professional Applications & Engineering Value
This 316 Stainless Steel Phillips Pan Head Screw is engineered to solve critical challenges in corrosive and high-stress industrial environments. The passivated finish on the 316 stainless steel significantly enhances its resistance to chemicals, saltwater, and other aggressive agents, preventing premature failure and reducing maintenance costs. The fully threaded 1/4"-20 UNC coarse thread ensures maximum grip and load distribution, which is vital for structural integrity in assemblies subjected to vibration and dynamic loads. Its 80,000 psi tensile strength makes it a heavy-duty fastener suitable for machinery, marine equipment, chemical processing plants, and outdoor infrastructure, where corrosion resistance and long-term durability are non-negotiable for operational safety and efficiency.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC thread with a Class 2A thread fit for standard tolerance and reliable mating. It is manufactured in compliance with the ASME B18.6.3 standard, ensuring dimensional accuracy and performance consistency. The product is also certified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming its adherence to environmental and safety regulations regarding hazardous substances.
