S-92239A350 10-24 Thumb Nuts

Key Features & Benefits at a Glance

• Tool-free installation and removal with wing-shaped head design for rapid manual tightening in hard-to-reach or time-sensitive applications
• Enhanced load distribution and joint stability thanks to the integrated 5/8" flat flange, reducing surface pressure and preventing loosening under vibration
• Superior corrosion resistance provided by the black zinc alloy coating, extending service life in demanding industrial environments
• Reliable coarse thread engagement with 10-24 UNC thread and Class 2B fit, ensuring quick, secure fastening even with minor misalignments
• Durable, long-lasting performance from robust alloy construction, capable of withstanding repeated assembly cycles without stripping
• Wide compatibility with standard 10-24 UNC male threads, making it a versatile replacement or upgrade for existing fastener systems

Professional Applications & Engineering Value

This black zinc alloy flanged thumb nut is engineered to solve critical challenges in maintenance, prototyping, and equipment assembly where tool access is limited or speed is essential. The wing nut profile allows operators to securely fasten and release components by hand, drastically reducing downtime during adjustments or repairs. The flat flange design increases the bearing surface, distributing clamp load more effectively to protect soft materials and maintain tension in high-vibration settings like machinery, automotive, or electrical enclosures. Its 10-24 UNC coarse thread and Class 2B fit provide consistent, reliable performance with standard bolts, ensuring interchangeability and reducing the risk of cross-threading during quick, tool-free installations.

Specification Summary & Compliance

This thumb nut features a 10-24 UNC coarse thread with Class 2B internal thread fit and right-hand direction, manufactured to standard inch dimensions. The flange measures 5/8" in diameter with 0.05" thickness, and the overall height is 29/64". The component is produced from a black zinc alloy for durability and corrosion protection, conforming to industry standards for thumb nuts and general purpose fasteners. It is designed to meet common industrial requirements and is RoHS and REACH compliant for safe use in various applications.
