S-92311A335 1/4"-28 x 7/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for longevity in harsh industrial environments
• Exceptional holding power through Class 3A thread fit precision, ensuring vibration-resistant connections
• Enhanced torque transmission with 1/8" hex drive design, preventing tool slippage during installation
• Maximum grip penetration from the cup point tip, creating permanent seating on shafts and components
• Consistent mechanical performance with Rockwell B80 hardness, maintaining structural integrity under load
• Space-saving installation through headless design, ideal for confined assemblies and flush mounting
• Reliable fine threading (28 TPI) for precise adjustment and superior resistance to loosening

Professional Applications & Engineering Value

These 18-8 stainless steel set screws deliver critical engineering solutions where vibration resistance and corrosion protection are paramount. The cup point design bites deeply into mating surfaces, preventing rotational slippage in high-torque applications like motor shafts, gear assemblies, and precision machinery. With Class 3A thread fit and UNF fine threading, they maintain clamping force under dynamic loads while the hex headless configuration allows flush mounting in space-constrained designs. The Rockwell B80 hardness ensures the 1/8" hex drive withstands repeated installation without deformation, making these set screws ideal for maintenance-intensive industrial environments.
