S-90181A836 10-32 x 1 1/2" Thumb Screws

Key Features & Benefits at a Glance

• Enhanced manual torque application with spade head design (3/8" height × 9/16" width) for superior grip without tools
• Exceptional durability in demanding environments through hardened steel construction with Rockwell B55 hardness
• Reliable load-bearing performance with 40,000 psi tensile strength for industrial applications
• Precise thread engagement with Class 2A fit and 10-32 UNF fine threads for secure fastening
• Full-length threading versatility allowing installation at any point along the 1 1/2" length
• Environmental compliance assurance with RoHS 3 (2015/863/EU) certification
• Standardized compatibility with right-hand UNF thread system for easy replacement and integration

Professional Applications & Engineering Value

This 10-32 UNF thumb screw delivers critical engineering advantages in industrial settings where tool-less access and repeated adjustments are required. The spade head design provides maximum surface contact for hand-tightening applications in electronic enclosures, machinery guards, and access panels. Manufactured from hardened steel with Rockwell B55 hardness, it resists deformation during high-frequency manual operations. The fully threaded 1 1/2" length and Class 2A thread fit ensure consistent engagement in threaded inserts and tapped holes, while the fine UNF threading maintains vibration resistance in dynamic environments. These features collectively solve common pain points of stripped threads, insufficient torque application, and material fatigue in maintenance-heavy applications.

Specification Summary & Compliance

This thumb screw maintains Class 2A thread fit tolerance per UNF standards with precise 10-32 fine threading. Manufacturing complies with inch system specifications including 0.19" thread diameter and right-hand thread direction. The component meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions, ensuring environmental safety in electronic and industrial applications. Full threading extends across the entire 1 1/2" length with consistent mechanical properties verified through 40,000 psi tensile strength testing.
