📌 Product Overview
The Strongest Link in Your Brake Assembly.
A loose brake rod means a failing brake system. Victory Technology’s Hex Coupling Nuts (also known as Extension Nuts or Long Nuts) are engineered to provide a secure, vibration-proof connection between the brake chamber push rod and the slack adjuster linkage.
Manufactured in our Zhuji Aoke facility from High-Tensile Carbon Steel, these nuts feature an elongated body design (DIN 6334 standard). This provides maximum thread engagement, ensuring that even under the immense stress of heavy braking and road vibration, the connection remains solid.1 Finished with Zinc Plating, they offer essential protection against chassis corrosion.
🔹 Why Choose Victory Coupling Nuts?
- ✅ Maximum Thread Engagement:Safety requires strength. Our “Long Nut” design provides 2x to 3x more thread contact than a standard nut. This distributes the load evenly across the threads, preventing stripping or pull-out during panic stops.2
- ✅ High Vibration Resistance:Trucks vibrate. Standard nuts can back off. The extra length and mass of our coupling nut create friction and stability, ensuring the brake rod adjustment stays exactly where you set it.
- ✅ Corrosion-Resistant Finish:Located under the truck, these parts face water, salt, and mud. We offer Zinc-Plated (Galvanized) or Stainless Steel options to prevent rust from seizing the threads, making future brake adjustments easier.
- ✅ Precision Machining:Smooth adjustment is key. Our threads (Metric or Imperial) are CNC machined to tight tolerances, ensuring they spin on smoothly by hand but lock tight when torqued.

❓ Frequently Asked Questions (FAQ)
Q: Do I need a jam nut with this?
A: Yes. For maximum safety in brake systems, we always recommend using a standard “Jam Nut” against the coupling nut to lock it in place permanently.
Q: What is the difference between Metric and Imperial?
A: Metric (e.g., M16) is common on modern European and some US trucks. Imperial (e.g., 1/2″-20 UNF) is common on older American trailers. Please verify your push rod thread before ordering.
Q: Can I use this to repair a broken rod?
A: Yes, coupling nuts are frequently used in repair shops to splice or extend threaded rods that have been cut too short.3
