S-90876A146 10-24 Thumb Nuts

Key Features & Benefits at a Glance

• Superior manual grip with standard wing profile for easy hand-tightening without tools
• Exceptional durability through iron construction resisting wear in industrial environments
• Reliable coarse threading with UNC 10-24 specification for faster assembly and reduced cross-threading risk
• Precise thread engagement with Class 2B fit ensuring consistent performance and vibration resistance
• Optimized dimensions (3/8" base, 1/2" height) providing stable seating and sufficient tightening surface
• Right-hand thread design compatible with standard fastening conventions for intuitive installation
• Robust construction supporting repeated tool-free assembly/disassembly cycles

Professional Applications & Engineering Value

This iron thumb nut solves critical challenges in maintenance-heavy and tool-limited environments. The UNC coarse thread configuration enables rapid installation even in poorly aligned applications, while the standard wing profile delivers maximum torque transmission for hand-tightening operations. Engineered with Class 2B thread fit, it maintains consistent clamping force in vibrating equipment, electrical enclosures, and machinery guards. The 3/8" base diameter provides stable bearing surface distribution, preventing loosening under dynamic loads. Ideal for industrial maintenance, prototype development, and applications requiring frequent adjustments where tools are impractical.
