S-92785A547 5/16"-18 x 5/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Maximum holding power with Class 3A thread fit ensuring precise, vibration-resistant connections in demanding applications
• Superior corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments
• Space-saving headless design allows flush mounting where clearance is limited
• Secure torque transmission via 5/32" hex socket drive preventing tool slippage during installation
• Enhanced grip penetration with 118° cone point angle for reliable seating on shafts and components
• Long-term durability supported by Rockwell B80 hardness maintaining mechanical integrity under load
• Broad compatibility with UNC coarse threads simplifying replacements and reducing inventory complexity

Professional Applications & Engineering Value

Engineered for precision shaft locking and component positioning, these 5/16"-18 UNC set screws address critical industrial challenges like vibration-induced loosening and corrosive degradation. The 18-8 stainless steel material provides inherent resistance to rust and chemicals, while the Class 3A thread fit and coarse UNC threading ensure rapid assembly with minimal cross-threading risks. The cone point with 118° angle bites securely into mating surfaces, making these headless hex socket screws ideal for permanent fastening in machinery, motor collars, and gear assemblies where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with Class 3A thread fit tolerances for consistent dimensional accuracy. UNC coarse threads (5/16"-18) with right-hand direction and 0.313" diameter ensure interchangeability. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmentally safe components for global supply chains.
