S-91375A797 10-32 x 3/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with fine 10-32 UNF threads and Class 3A fit for minimal backlash and reliable positioning in high-vibration environments
• Exceptional durability from zinc plated alloy steel construction with Rockwell C45 hardness, providing excellent resistance to wear and corrosion
• Secure installation using a compact 3/32" hex drive in a headless design, ideal for confined spaces where standard screw heads won't fit
• Enhanced grip and marking prevention with cup tip design that concentrates contact pressure while minimizing surface damage to components
• Right-hand thread direction ensures intuitive installation following industry-standard practices for maintenance efficiency
• Regulatory compliance with RoHS 3 and REACH environmental standards, making them suitable for global supply chains and sensitive applications
• Precision manufacturing to ASME B18.3 specifications, guaranteeing consistent dimensional accuracy and reliable performance batch after batch

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The zinc plated alloy steel construction provides superior corrosion resistance while maintaining Rockwell C45 hardness for lasting performance in demanding mechanical systems. The headless hex drive design allows installation in tightly spaced assemblies where traditional fastener heads would interfere, while the fine thread spacing creates maximum engagement strength for securing gears, pulleys, and collars on shafts. The cup tip concentrates clamping force to prevent slippage in high-torque applications, making these industrial set screws ideal for precision machinery, automotive components, and production equipment where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to exacting ASME B18.3 specifications with Class 3A thread fit for superior dimensional accuracy and consistent performance. The 10-32 UNF fine threads provide precise engagement while the 3/8" length offers versatile application coverage. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures these set screws meet the strictest international standards for hazardous substance restrictions.
