S-98625A436 6-80 x 1 1/2" Set Screws

Key Features & Benefits at a Glance

• Enhanced holding power through Class 3A precision thread fit for secure fastening in critical assemblies
• Superior corrosion resistance with 303 stainless steel construction for long-term reliability in harsh environments
• Space-saving headless design that allows flush mounting where clearance is limited
• Precise torque application with 5/64" hex drive for controlled installation without slippage
• Reduced component damage thanks to alloy steel ball tip that minimizes surface marring during engagement
• Exceptional thread engagement with 6-80 UNS ultra fine threads for vibration-resistant connections
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global market acceptance

Professional Applications & Engineering Value

This 6-80 ultra fine thread set screw delivers exceptional engineering value in applications requiring precise axial positioning and vibration resistance. The 303 stainless steel construction provides excellent corrosion resistance for demanding environments while maintaining machinability for custom applications. The headless hex design with 5/64" drive enables installation in confined spaces where traditional fasteners cannot operate. The alloy steel ball tip creates consistent point contact that prevents workpiece damage while maintaining secure positioning. Particularly valuable in precision instrumentation, optical equipment, and aerospace assemblies where Class 3A thread fit ensures repeatable accuracy and the ultra fine thread spacing provides superior resistance to vibrational loosening under dynamic loads.

Specification Summary & Compliance
