1. What is this? These 304 stainless steel coupling nuts are industrial-grade threaded connectors designed to securely join threaded rods, bolts, or studs in high-stress applications. Featuring a thickened walls, they provide superior load distribution for machinery assembly, garage workbenches, and structural works. Made from corrosion-resistant 304 stainless steel, these nuts withstand harsh environments while maintaining precision threading.
2. What will i get? Round Coupling Nuts
Threaded Size: M3x0.5mm;
Total Size: 6x4mm/0.24x0.2 Inch(ODxH);
Color: Silver;
Material: 304 Stainless Steel;
Package Include: 24Pcs x Hardware Nuts.
3. Are there any advantages of the product? 1. Industrial Strength: 304 stainless steel and polished surface offers tensile strength and resists rust, chemicals, and extreme temperatures.
2. Extended Design: longer than standard coupling nuts for deeper thread engagement, preventing rod slippage under vibration.
3. Universal Compatibility: Works with threaded rod – Great for scaffolding, automotive repairs, or furniture reinforcement.
4. How to use it? Align Threads: Match the nut’s internal threads to the rod/stud.
Hand-Start: Screw the coupling nut onto one rod end until finger-tight.
Add Second Rod: Insert the opposing rod and rotate clockwise to engage threads.
Final Tighten: Use a wrench (or adjustable wrench) to secure.
5. What should I notice? Avoid Cross-Threading: Ensure rods are perfectly aligned before tightening.
Material Compatibility: Pair only with stainless steel or coated carbon steel rods to prevent corrosion.
Storage: Keep in a dry toolbox – moisture may cause temporary thread binding (not rust).
