S-98001A157 M4 Weld Nuts

Key Features & Benefits at a Glance

• Enhanced welding precision with a low 0.8 mm barrel height and 5.2 mm diameter for minimal material displacement and strong, clean joints.
• Reliable thread performance due to Class 6H thread fit, ensuring consistent engagement and reducing the risk of cross-threading in M4 x 0.7 mm coarse threaded applications.
• Optimized space utilization with a compact rectangular base (22x11 mm) and low profile design, ideal for confined assembly areas.
• Durable steel construction provides excellent strength and corrosion resistance, suitable for demanding industrial environments.
• Simplified installation with a 5.6 mm pre-drilled hole compatibility, speeding up production and reducing labor time.
• Compliance assurance with REACH and RoHS 3 standards, guaranteeing safety and environmental responsibility in your supply chain.
• Versatile metric coarse threading (M4 x 0.7 mm) offers quick assembly and high resistance to vibration loosening in various machinery.

Professional Applications & Engineering Value

This low profile rectangular weld nut is engineered to address common challenges in automated welding and tight-tolerance assemblies. Its steel material and rectangular base provide superior stability and load distribution, preventing rotation during welding and under stress. The M4 x 0.7 mm coarse thread and Class 6H fit ensure reliable fastening in high-vibration environments like automotive frames, electrical enclosures, and machinery panels. By minimizing protrusion with a 0.8 mm barrel height, it reduces the risk of interference in compact designs, streamlining production while maintaining industrial-grade durability and compliance with global standards.
