S-92311A092 3-48 x 1/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Maximum holding power achieved through Class 3A thread fit and cup point tip design for secure fastening
• Easy installation and removal with 0.050" hex drive, requiring minimal clearance in confined spaces
• Excellent durability with Rockwell B80 hardness maintaining performance under repeated use
• Reliable coarse thread spacing (UNC) providing faster assembly and reduced cross-threading risk
• Space-saving headless design allowing flush mounting where protruding fasteners aren't feasible
• Industry compliance assurance meeting ASME B18.3 specifications for consistent quality and performance

Professional Applications & Engineering Value

This 3-48 UNC set screw delivers exceptional engineering value in precision assembly applications where space constraints and corrosion resistance are critical factors. The 18-8 stainless steel construction provides excellent resistance to oxidation and chemical exposure, making it suitable for manufacturing equipment, electronic enclosures, and machinery components exposed to demanding environments. The cup point tip creates deep indentations in shaft materials, preventing rotational slippage in pulley systems, gear assemblies, and coupling applications. The headless design with hex drive allows installation in counterbored holes where traditional screw heads would interfere, while the Class 3A thread fit ensures precise engagement with mating components for vibration-resistant fastening in automotive, aerospace, and industrial machinery applications.
