S-90876A140 8-32 Thumb Nuts

Key Features & Benefits at a Glance

• Tool-free installation with wing-shaped head for quick manual tightening and removal in tight spaces
• Durable iron construction provides reliable strength and corrosion resistance for industrial environments
• Precision Class 2B thread fit ensures smooth engagement and consistent clamping force with mating components
• Coarse UNC threading offers faster assembly and reduced cross-threading risk compared to fine threads
• Generous 1" wing span delivers superior grip and torque application without specialized tools
• Right-hand thread direction maintains standard rotation convention for intuitive installation
• Compact 1/2" height profile fits space-constrained applications while maintaining structural integrity

Professional Applications & Engineering Value

This iron wing thumb nut solves critical assembly challenges in maintenance-heavy industries where tool access is limited. The 8-32 UNC coarse thread configuration combined with Class 2B thread fit provides rapid engagement with mating fasteners while maintaining vibration resistance in equipment panels, access covers, and temporary fixtures. The standard wing nut profile enables operators to achieve proper torque through manual operation alone, eliminating downtime from misplaced tools in manufacturing floors, electrical enclosures, and conveyor systems. The 1/4" base diameter offers optimal bearing surface for secure fastening without compromising the compact 1" width that fits standard wrench clearance requirements.
