S-90594A024 1/4"-20 Weld Nuts

Key Features & Benefits at a Glance

• Reliable Welding Performance: Standard barrel profile ensures consistent weld penetration and strong, permanent attachment in structural applications.
• Durable Steel Construction: Made from robust steel for excellent strength and resistance to vibration loosening in demanding environments.
• Easy Alignment & Installation: Rectangular base shape provides stability and prevents rotation during the welding process, speeding up assembly.
• Optimized Coarse Thread Design: 1/4"-20 UNC coarse thread allows for faster installation and is less prone to clogging with debris compared to fine threads.
• Precision Thread Fit: Class 1B internal thread ensures smooth mating with Class 2A external fasteners, reducing the risk of cross-threading.
• Compact, Heavy-Duty Design: With a 5/16" barrel diameter and 1/4" height, this nut offers a low-profile yet strong solution for space-constrained assemblies.
• Compliant for Global Use: Meets RoHS 3 and REACH standards, ensuring suitability for regulated markets and environmentally conscious manufacturing.

Professional Applications & Engineering Value

This rectangular steel weld nut is engineered to solve common fastening challenges in heavy-duty fabrication and assembly. Its rectangular base and standard barrel profile provide a larger surface area for welding, ensuring a high-strength bond that resists torque and shear forces in frameworks, machinery, and vehicle chassis. The 1/4"-20 UNC coarse thread is ideal for rapid assembly in industrial settings, reducing installation time while maintaining a secure connection. Made from durable steel, it withstands harsh conditions, including vibration and thermal cycling, making it a reliable choice for automotive, construction, and metalworking applications. The design prioritizes ease of use, allowing for quick alignment and reducing production downtime.

Specification Summary & Compliance
