S-94579A850 M4 Weld Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Secure, vibration-resistant fastening with Class 6H thread fit ensuring precise engagement and reduced loosening risks
• Space-saving installation thanks to low barrel profile (0.8 mm height) ideal for confined assembly areas
• Stable welding performance with rectangular base design (16x11 mm) providing superior surface contact and alignment
• Quick, reliable threading with M4 coarse pitch (0.7 mm) enabling faster assembly and reduced cross-threading incidents
• Optimized hole compatibility designed for 5.3 mm diameter holes, minimizing installation errors and rework
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial supply chain integration

Professional Applications & Engineering Value

This low profile rectangular weld nut delivers critical solutions for industrial assembly challenges where space constraints and corrosion resistance are paramount. The zinc-plated steel construction provides essential protection against oxidation in manufacturing facilities, automotive frames, and electrical enclosures. Its rectangular base (16x11 mm) offers increased welding surface area compared to standard shapes, preventing rotation during installation and maintaining alignment in automated welding processes. The M4 coarse thread (0.7 mm pitch) combined with Class 6H thread fit ensures reliable engagement with mating components, reducing assembly time and eliminating the need for additional locking mechanisms. This metric weld nut is engineered specifically for high-volume production environments where consistent performance and regulatory compliance are non-negotiable requirements.

Specification Summary & Compliance

Manufactured to precise metric dimensions with barrel profile (5.2 mm diameter, 0.8 mm height) and rectangular base (16×11×2.4 mm). Thread specifications include M4 right-hand metric thread with 0.7 mm coarse pitch and Class 6H thread fit per ISO standards. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC requirements. Designed for optimal performance with 5.3 mm diameter mounting holes in welded assembly applications.
