S-94842A103 3/8"-16 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance thanks to the integrated 3/4" flange that acts as a built-in washer, distributing load and preventing loosening under dynamic loads.
• Enhanced durability and corrosion protection from the zinc-plated steel construction, ensuring long-term performance in harsh industrial environments.
• High-strength performance with a Grade 5 rating, providing reliable clamping force for demanding heavy-duty applications.
• Easy and quick installation with a standard external hex drive and coarse 3/8"-16 UNC threads, reducing assembly time and effort.
• Precise and reliable thread engagement due to the Class 2B thread fit, minimizing the risk of cross-threading and ensuring a secure connection.
• Compliance with environmental and safety standards, being REACH and RoHS 3 compliant, making it suitable for regulated industries.
• Versatile industrial use with a standard hex profile and right-hand thread, compatible with common tools and fastening systems.

Professional Applications & Engineering Value

This Grade 5 zinc-plated steel flange nut is engineered to address common challenges in heavy-duty industrial applications, such as machinery, automotive assemblies, and structural frameworks, where vibration and dynamic stresses can lead to fastener failure. The 3/4" flange diameter provides a larger bearing surface, effectively distributing pressure and reducing the risk of surface damage or loosening over time. Combined with coarse UNC threads and a Class 2B fit, it ensures quick, secure installation and reliable performance in high-vibration environments. The zinc plating offers excellent corrosion resistance, extending service life and reducing maintenance costs, while the external hex drive allows for easy torque application with standard tools, streamlining assembly processes in B2B procurement scenarios.

Specification Summary & Compliance
