S-98520A102 8-32 Thumb Nuts

Key Features & Benefits at a Glance

• Secure vibration-resistant locking thanks to the nylon insert that maintains grip under dynamic loads
• High-temperature resilience with the insert rated for continuous use up to 225°F (107°C)
• Quick hand-tightening installation enabled by the wing-style head design, reducing tool dependency
• Precise thread engagement with Class 2B fit and coarse 8-32 UNC threads for reliable fastening in industrial settings
• Corrosion-resistant durability from the zinc alloy construction, extending service life in harsh environments
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable usage
• Broad compatibility with standard UNC coarse-threaded components, simplifying inventory and replacements

Professional Applications & Engineering Value

This nylon insert locking thumb nut delivers critical vibration resistance in machinery, electronics, and automotive assemblies where loosening under stress is a common failure point. The zinc alloy body combined with the standard wing profile allows for rapid manual adjustments without tools, ideal for maintenance panels, access covers, and frequently disassembled equipment. Its coarse UNC threads and Class 2B fit ensure consistent clamping force, while the non-metallic insert dampens shocks and thermal expansion effects up to 225°F. Engineers value this thumb nut for reducing downtime and enhancing safety in industrial applications requiring both convenience and reliability.
