S-94909A029 1/4"-20 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through thread forming locking action that maintains secure fastening in high-motion environments
• Built-in flange eliminates need for separate washers, reducing assembly time and component count while providing wider bearing surface
• Exceptional temperature performance with reliable operation from -40° to 185°F for both indoor and outdoor applications
• Corrosion-resistant Nylon 6/6 construction ensures long service life in humid, chemical, or electrically sensitive environments
• Lightweight non-magnetic properties make these nuts ideal for electronics, marine, and aerospace applications
• Standard UNC coarse threads provide faster installation and reduced cross-threading risk compared to fine thread alternatives
• External hex drive design enables easy installation with common tools while maintaining consistent torque application

Professional Applications & Engineering Value

This Nylon 6/6 flange lock nut combines material advantages with innovative thread forming locking technology to solve critical industrial fastening challenges. The white plastic construction offers excellent electrical insulation and corrosion resistance, making it ideal for electrical enclosures, control panels, and marine equipment where metal fasteners would cause galvanic corrosion. The integrated 1/2" flange distributes clamping force over a wider area, preventing damage to soft materials and reducing stress concentration. With UNC coarse threads and right-hand thread direction, these nuts provide reliable performance in vibration-prone applications such as machinery, automotive assemblies, and conveyor systems, where maintaining clamp load is essential for operational safety and reduced maintenance intervals.

Specification Summary & Compliance

This 1/4"-20 flange lock nut features standard UNC coarse threads with Class 2A fit for consistent engagement. Manufactured from premium Nylon 6/6 plastic with dimensions including 27/64" width, 9/32" height, and 1/2" flange diameter. The nut complies with RoHS 3 (2015/863/EU) environmental standards and is designed for use in commercial and industrial applications requiring non-conductive, non-corrosive fastening solutions.
