Key Features & Benefits at a Glance
- Superior vibration resistance through the nylon insert that maintains locking force even under dynamic loads
- Enhanced corrosion protection with zinc yellow-chromate plating for extended service life in harsh environments
- High-temperature performance with nylon insert rated for continuous operation up to 250°F (121°C)
- Distributed load bearing thanks to the 0.81" flange diameter that reduces surface pressure and prevents damage
- Reliable coarse threading with UNC 3/8"-16 pattern for quick installation and reduced cross-threading risk
- Industrial-grade strength meeting Grade G specifications for demanding mechanical applications
- Secure external hex drive for easy installation with standard tools while maintaining precise torque control
Professional Applications & Engineering Value
This Grade G nylon insert flange lock nut delivers critical vibration resistance in industrial equipment, automotive assemblies, and machinery where secure fastening is paramount. The combination of zinc yellow-chromate plated steel construction and 0.81" flange diameter addresses common challenges of corrosion and surface damage while distributing clamp load effectively. The UNC coarse thread design ensures rapid installation in production environments, while the nylon insert locking mechanism maintains tension despite constant vibration or thermal cycling up to 250°F. This engineered solution prevents costly downtime in heavy-duty applications where traditional nuts would loosen under stress.
Specification Summary & Compliance
Manufactured to precise Class 2B thread fit standards with UNC 3/8"-16 coarse threading and right-hand direction. The nut features a 9/16" width across flats and 13/32" height with 0.06" flange thickness. Complies with industry standards for Grade G strength classification and is suitable for applications requiring RoHS and REACH compliance. The external hex drive style ensures compatibility with standard wrenching tools while maintaining specified torque values.
