• Exceptional holding power achieved through the cup point design that bites securely into mating surfaces
• Precise thread engagement with Class 3A fit ensuring tight tolerances and reliable fastening in critical applications
• Easy installation in confined spaces using the 3/32" hex drive headless design
• Enhanced durability from Rockwell B80 hardness providing excellent resistance to wear and deformation
• Reliable fine threading with 10-32 UNF right-hand threads offering superior vibration resistance
• Full regulatory compliance meeting ASME B18.3 standards and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

This 10-32 UNF 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 protection against rust and chemical exposure, making it ideal for machinery, automotive components, and electronic enclosures operating in demanding environments. The cup point design creates permanent seating by concentrating pressure on a small contact area, preventing shaft slippage in pulley systems, gears, and collars. The hex headless configuration with 3/32" drive allows for installation in tight spaces where conventional screw heads would interfere, while the fine thread pitch ensures superior vibration resistance compared to coarse-thread alternatives. This combination of material strength, precise Class 3A thread fit, and specialized point geometry solves common industrial challenges of component creep, corrosion-induced failure, and space-limited assembly requirements.

Specification Summary & Compliance

This precision set screw maintains Class 3A thread fit tolerances for superior engagement and meets ASME B18.3 manufacturing specifications. The 10-32 UNF fine thread with right-hand direction ensures compatibility with standard components. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. The combination of precise dimensional control and material certification makes this fastener suitable for quality-critical industrial applications requiring documented compliance.
