S-91772A153 6-32 x 1" ASME B18.6.3 Stainless Steel Pan Head Phillips Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from passivated 18-8 stainless steel construction, ideal for humid or chemically aggressive environments
• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for reliable load-bearing performance
• Optimized drive engagement through Phillips No. 2 drive design, preventing cam-out during high-torque installation
• Precision thread compatibility with UNC coarse spacing and Class 2A fit, ensuring secure fastening in industrial assemblies
• Full-length threading provides maximum grip along the entire 1" shaft length for enhanced joint stability
• Regulatory compliance assurance meeting ASME B18.6.3 manufacturing standards and environmental directives (RoHS 3, REACH)
• Streamlined pan head profile offers low-profile seating with rounded edges to minimize snagging in confined spaces

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these passivated 18-8 stainless steel machine screws deliver critical corrosion protection where moisture, chemicals, or temperature variations would degrade ordinary fasteners. The UNC coarse thread configuration combined with Class 2A thread fit ensures rapid installation and vibration resistance in metal assemblies, electrical enclosures, and machinery frames. The pan head design with Phillips No. 2 drive provides reliable torque transmission while maintaining a low-profile presence—ideal for applications where clearance is limited but high clamp force is required. These fully threaded screws maintain consistent holding power across the entire fastener length, preventing joint loosening in dynamic load conditions common in manufacturing equipment, automotive components, and outdoor infrastructure.

Specification Summary & Compliance

This 6-32 x 1" machine screw features UNC coarse threads with Class 2A dimensional tolerance per ASME B18.6.3 specifications. Manufacturing compliance includes ASME B18.6.3 for dimensional standards, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) for chemical safety regulations. The passivated 18-8 stainless steel construction ensures consistent mechanical properties with 70,000 psi tensile strength and Rockwell B70 hardness verification.
