S-91772A102 0-80 x 1" ASME B18.6.3 Stainless Steel Pan Head Phillips Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with passivated 18-8 stainless steel construction, ideal for harsh environments and long-term reliability
• Superior strength and durability with 70,000 psi tensile strength and Rockwell B70 hardness, preventing stripping and deformation under load
• Precise thread engagement through Class 2A thread fit and UNF fine threads, ensuring secure fastening in precision components
• Easy installation and removal with Phillips No. 0 drive and rounded pan head design, reducing assembly time and tool slippage
• Full threading along the 1" length provides maximum grip and uniform stress distribution across the entire fastener
• Compliance with major industry standards including ASME B18.6.3, RoHS 3, and REACH, guaranteeing safety and regulatory acceptance
• Versatile rounded head profile offers a low-profile, finished appearance while minimizing snagging in confined spaces

Professional Applications & Engineering Value

These 0-80 UNF rounded head screws deliver critical performance in precision engineering and industrial applications where failure is not an option. The passivated 18-8 stainless steel provides excellent resistance to oxidation and chemical exposure, making them ideal for electronics, medical devices, aerospace assemblies, and marine equipment. The fine thread design and Class 2A fit ensure vibration resistance and precise alignment in thin materials or delicate components, reducing the risk of cross-threading. With a Phillips drive and pan head style, they enable efficient installation in automated or manual processes, while the fully threaded shank maximizes holding power in high-stress applications. This combination addresses common pain points like corrosion-induced failure, thread stripping, and compliance documentation challenges.

Specification Summary & Compliance

Manufactured to exacting standards, these screws feature UNF 0-80 fine threads with Class 2A thread fit for consistent dimensional accuracy. They comply with ASME B18.6.3 specifications for mechanical fasteners and meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they are free from hazardous substances. The passivated surface treatment enhances corrosion resistance without compromising the mechanical properties, supporting use in regulated industries requiring full material traceability and compliance documentation.
