S-91346A250 3/4"-10 Flange Nuts

Key Features & Benefits at a Glance

• Superior Load Distribution - The large 1 5/8" flange diameter and 1/4" thickness eliminate the need for a separate washer, providing a wider bearing surface to prevent surface damage and distribute loads more effectively.
• Exceptional Corrosion Resistance - Manufactured from 18-8 Stainless Steel, this nut offers excellent resistance to rust and corrosion, ensuring long-term reliability in demanding industrial and outdoor environments.
• Precision Leveling Capability - Engineered with a maximum correction of 1 1/2°, this nut provides precise and stable leveling adjustments for machinery, equipment, and structural components.
• Reliable & Fast Assembly - The coarse UNC thread and Class 2B thread fit enable quicker installation and a secure, reliable connection that is less prone to cross-threading.
• Durable External Hex Drive - The standard external hex profile allows for high-torque application with common tools, ensuring a tight, vibration-resistant fit.
• Environmental & Regulatory Compliance - Meets RoHS 3 (2015/863/EU) compliance, making it suitable for use in regulated industries and environmentally conscious projects.
• Material Consistency - Both the nut and integrated flange/washer are made from the same 18-8 Stainless Steel, ensuring uniform strength and corrosion performance throughout the assembly.

Professional Applications & Engineering Value

This heavy-duty flange leveling nut is engineered to solve critical stability and alignment challenges in industrial and construction settings. Its integrated 1 5/8" flange acts as a built-in washer, providing a large bearing surface that prevents pull-through and distributes clamping force over a wider area. This is crucial for protecting softer materials and ensuring the longevity of the assembly. The 18-8 Stainless Steel construction delivers consistent corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor weather, such as in structural steelwork, machinery mounting, and conveyor systems. The 3/4"-10 UNC coarse thread and Class 2B fit are specifically chosen for their ability to handle high loads and allow for rapid, reliable installation, even in less-than-ideal field conditions. This combination of a robust external hex drive and precision leveling capability makes it an indispensable component for engineers and contractors who require a durable, all-in-one fastening and leveling solution.
