• Space-saving low-profile barrel (3/32" height) ideal for applications with limited clearance while maintaining structural integrity
• Reliable coarse thread engagement with 5/16"-18 UNC Class 2B threads ensuring smooth assembly and reduced cross-threading risk
• Optimized material strength from durable steel construction that withstands industrial stresses and vibration
• Secure weld positioning through precise 23/64" barrel diameter and 3/8" hole compatibility for accurate placement
• Environmental compliance assurance with REACH and RoHS 3 certifications meeting international regulatory standards
• Right-hand thread convenience for standard installation procedures and compatibility with common fastening tools

Professional Applications & Engineering Value

This low-profile rectangular weld nut addresses critical challenges in industrial assembly where space constraints and vibration resistance are paramount. The steel construction combined with the rectangular base design provides exceptional stability during welding operations, preventing movement that could compromise joint integrity. The 5/16"-18 UNC coarse threads with Class 2B fit ensure rapid installation while maintaining precise thread engagement, reducing assembly time in high-volume manufacturing environments. Particularly valuable in automotive frames, machinery enclosures, and structural frameworks, this weld nut's low-profile barrel and generous 63/64" base length distribute stress effectively across welded surfaces, enhancing the durability of critical connections subject to dynamic loads and thermal cycling.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit tolerance ensuring consistent performance across applications. The UNC coarse thread specification (5/16"-18) follows established industrial standards for reliable compatibility. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations guarantees material safety and regulatory acceptance. The weld nut is engineered for 3/8" diameter mounting holes with right-hand thread direction conforming to industry-standard installation practices.
