About this item
- PRECISE THREADS: Our factory utilizes state-of-the-art threading machines and adheres to strict manufacturing standards and specifications for threads. In addition, our quality control team inspects, tests, and screens the threads to ensure that the bolts and channel nuts you receive are free from issues such as missing threads, crossed threads, uneven threads, or burrs, allowing for easy and smooth installation.
- PREMIUM SPRING SECURE HOLD: When installing, the spring provides reliable support to keep the strut spring nut in place. Once installed, the high-quality elasticity of the spring ensures a strong connection between the spring channel nut and strut channel, reducing the risk of loosening even under vibration or heavy loads.
- ANTI-SLIP GRIP STRIPS ON NUT BACKING: When the strut channel nut is tightened, these anti-slip grooves provide additional friction, allowing the channel nut to grip the strut channel more effectively. This prevents the spring nut from loosening or slipping on its own, ensuring a secure connection that remains sturdy and safe even under vibration or heavy loads.
- THICKENED GALVANIZED PLATING: In addition to its aesthetic appeal, thickened zinc plating provides excellent corrosion protection, safeguarding the product from oxidation and corrosion. This ensures that the bolts and channel nuts have an extended lifespan even in damp, acidic, or alkaline environments. For outdoor applications, the thicker zinc plating is especially crucial.
