S-90955A103 M8 Weld Nuts

Key Features & Benefits at a Glance

• Enhanced alignment tolerance with floating nut design that compensates for minor positioning errors during welding
• Superior thread reliability with Class 6H thread fit ensuring consistent engagement and reduced cross-threading risks
• Optimized welding performance through rectangular base design (50.8×19.8mm) providing maximum surface contact for secure bonds
• Exceptional durability with C1008/C1010 steel construction offering high tensile strength and corrosion resistance
• Simplified installation with coarse M8×1.25mm threads enabling quick assembly in high-vibration environments
• Regulatory compliance assurance meeting both RoHS 3 and REACH standards for global industrial applications
• Versatile mounting capability with 1.27mm base thickness allowing deformation-free welding across various material gauges

Professional Applications & Engineering Value

This M8 metric weld nut addresses critical challenges in industrial assembly where thread alignment precision and welding integrity are paramount. The rectangular floating nut design incorporates a movable insert that automatically adjusts to bolt entry angles, eliminating misalignment issues common in fixed-thread fasteners. Manufactured from C1008/C1010 steel, the nut maintains structural integrity under thermal stress during welding operations while providing reliable Class 6H thread fit for repeated disassembly cycles. The 50.8×19.8mm base distributes welding heat evenly, preventing warping in thin-gauge materials. Ideal for automotive frames, machinery panels, and structural steel applications where coarse metric threads ensure rapid assembly without compromising joint security.

Specification Summary & Compliance

This rectangular weld nut features precision M8×1.25mm coarse threads with Class 6H thread fit per ISO metric standards, ensuring dimensional accuracy across production batches. The 50.8mm length × 19.8mm width × 1.27mm thick base maintains flatness tolerance during welding operations. Manufacturing complies with REACH (EC 1907/2006) substance restrictions and RoHS 3 (2015/863/EU) directives, with full material traceability using C1008/C1010 steel components. The right-hand thread direction follows international convention for compatibility with standard metric threaded fasteners.
