S-90955A115 5/16"-18 Weld Nuts

Key Features & Benefits at a Glance

• Enhanced Misalignment Compensation: Floating nut design allows for slight positional adjustments during installation, reducing assembly time and preventing cross-threading in demanding welding applications.
• Robust Structural Integrity: Made from C1008/C1010 steel, this weld nut provides excellent strength and durability for heavy-duty industrial environments.
• Reliable Thread Engagement: Class 2B thread fit ensures consistent, secure fastening with standard 5/16"-18 UNC bolts, minimizing the risk of loosening under vibration.
• Optimized Weld Surface: The rectangular base (2" x 25/32") with a thin 1/16" profile offers a large, stable contact area for strong, clean welds.
• Broad Compatibility: Coarse UNC threads are ideal for quick assembly and are widely used with common inch-series bolts, enhancing versatility across various machinery and structures.
• Environmental and Regulatory Safety: Full compliance with RoHS 3 and REACH standards guarantees that the nut is free from hazardous substances, supporting sustainable and safe manufacturing practices.
• Secure Retention: The integrated steel retainer firmly holds the floating nut, preventing displacement during handling and welding operations for precise, repeatable results.
