Limited Life Range Test ≥ 2000000 Stress Cycles Without Damage
Neutral Salt Spray Test ≥ 192H
For detailed test report, please check SGS or TUV.
1. Unique 12 petals cornucopia head shape highlights the super forging one-time forming craftsmanship, which can not be presented in a later turning process.
2. Forged with SCM440 High Strength Steel, the comprehensive performance is obviously better than SCM435, far better than COMMON 35CrMo and 40Cr in the market.
(Since the high price and higher requirements for processing equipment and molds of the SCM440 high strength steel, the production cost is much higher than ordinary steel, our products are mainly used for high performance and high strength products. Please refer to the official website for the BONOSS bolt material identification report provided by TUV and SGS.)
3. The spacer structure effectively eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between hub and shaft head while driving.
4. The spacer material is forged 7075T6 aluminum alloy, which is completely better than 6061 series aluminum alloy, meanwhile, meets the dual needs of lightweight and performance.
5. Bolt large diameter shaft design, which means the diameter of the rod is larger than the diameter of the thread, for improving the ultimate performance of bolts.
6. Ten-year warranty, confidence from our professionalism and high quality.
