S-91783A203 8-32 x 1 1/2" ASME B18.6.3 Stainless Steel Round Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ensuring long-term reliability in harsh environments
• Exceptional mechanical strength with 100,000 psi tensile strength and Rockwell B100 hardness for heavy-duty industrial applications
• Reliable thread engagement through UNC coarse threading and Class 2A fit, providing secure fastening with reduced cross-threading risk
• Full-threaded design maximizes grip length and load distribution across the entire fastener
• Standard slotted drive enables quick installation with common tools while maintaining rounded head aesthetics
• Industry-standard compliance with ASME B18.6.3 ensures dimensional accuracy and interchangeability
• Environmental responsibility through RoHS 3 and REACH compliance for sustainable manufacturing practices

Professional Applications & Engineering Value

These 8-32 UNC coarse thread rounded head screws deliver critical performance advantages for industrial assembly applications where corrosion resistance and mechanical integrity are paramount. The 18-8 stainless steel composition combined with passivated surface treatment creates a protective oxide layer that significantly extends service life in moisture-prone environments. The fully threaded design ensures maximum thread engagement across the entire 1½" length, distributing clamp loads evenly while preventing joint loosening under vibration. The rounded head profile with slotted drive offers both aesthetic appeal and practical installation, making these fasteners ideal for machinery, electrical enclosures, and structural assemblies requiring ASME B18.6.3 compliance and reliable 100,000 psi tensile strength performance.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerances and UNC coarse threading specifications. These screws conform to ASME B18.6.3 manufacturing standards and meet environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) requirements. The combination of Rockwell B100 hardness and controlled thread geometry ensures consistent performance across industrial applications.
