S-92311A430 10-32 x 5/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Precise thread engagement with Class 3A fit ensuring reliable, vibration-resistant fastening in critical applications
• Enhanced torque transmission through the 3/32" hex drive design, preventing tool slippage and damage
• Excellent material durability with Rockwell B80 hardness providing optimal strength without brittleness
• Secure component positioning via the cup tip design that minimizes surface damage while maintaining firm contact
• Space-saving installation with headless configuration ideal for confined spaces and flush mounting requirements
• Industry-standard compatibility with UNF fine threads (10-32) ensuring interchangeability with existing systems

Professional Applications & Engineering Value

This 10-32 UNF set screw delivers exceptional engineering value in applications requiring precise component alignment and secure fastening. The 18-8 stainless steel composition provides excellent corrosion resistance, making it ideal for machinery exposed to moisture, chemicals, or outdoor elements. The Class 3A thread fit ensures tighter tolerances than standard fasteners, preventing loosening under vibration in automotive assemblies, precision instruments, and industrial equipment. The cup tip design concentrates pressure on a small contact area while minimizing surface marring, perfect for securing gears, pulleys, and collars on shafts. With its headless configuration and 3/32" hex drive, this set screw offers reliable installation in space-constrained applications where protruding fastener heads are unacceptable, maintaining both functional integrity and aesthetic requirements.

Specification Summary & Compliance

This precision set screw features 10-32 UNF fine threads with Class 3A thread fit for superior dimensional accuracy and engagement. Manufactured to ASME B18.3 specifications with right-hand thread direction and 5/8" length. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting the latest environmental regulations for industrial components.
