S-94640A882 1/4"-28 Weld Nuts

Key Features & Benefits at a Glance

• Exceptional Strength and Durability: Crafted from 4130 alloy steel, this weld nut offers superior resistance to stress and wear, ensuring long-lasting performance in demanding industrial environments.
• Precise Left-Hand Threading for Secure Fastening: The left-hand UNF fine thread (1/4"-28) provides reliable, reverse-direction locking, ideal for applications where standard right-hand threads may loosen under vibration.
• Optimized for Tube Assemblies: Specifically designed for 1/2" OD tubing with a 0.058" wall thickness, ensuring a perfect fit and secure connection in tube end systems.
• Superior Thread Fit for Smooth Assembly: Class 2B thread fit guarantees consistent, easy engagement with mating components, reducing installation time and preventing cross-threading.
• Fully Threaded Design for Maximum Engagement: The 1" fully threaded length allows for deeper, more secure fastening, distributing load evenly and enhancing joint integrity.
• Compliance with Environmental Standards: Meets RoHS 3 and REACH regulations, ensuring safe use in various industries without harmful substances.
• Fine Thread Spacing for Enhanced Grip: The UNF fine thread profile offers improved clamping force and vibration resistance compared to coarse threads, critical for high-stress applications.
