1. Unique 12 petals cornucopia head shape highlights the super forged one-time forming craftsmanship, which cannot be presented in a later turning process.
   
   
   
2. Forged with Japanese SCM440 high strength alloy steel, The comprehensive performance is obviously better than SCM435, far better than COMMON 35CrMo and 40Cr in the market. (Since the high raw price and higher requirements for processing and molds of the SCM440, the production cost of the stud is much higher than ordinary material.)
   
   
   
3. The swivel washer type bolt structure effectively eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxiality deviation between wheel and hub axle while driving.
   
   
   
4. The swivel washer made of forged aluminum alloy 7075-T6, which is completely better than 6061 series aluminum alloy, meanwhile, meets the dual needs of lightweight and performance.
   
   
   
5. Bolt large diameter shank design, which means the diameter of the shank is larger than the diameter of the thread, for improving the ultimate performance of bolts.
   
   
   
6. 10 Years warranty, confidence from our professionalism and high quality.

Limited Life Range:

Limited Life Range is very important for Long life drive. Normally, The 10.9 Grade Wheel Bolts/Studs Only test the Tensile, Proof Load, Hardness. they are for Strength but NOT for Toughness, but in BONOSS view, the Toughness is as important as Strength .So, BONOSS Bolts/Studs passed 1 MILLION and 2 MILLION Times Fatigue Strength Test, For Safe, For long life Safe.

 Anti-Rust Bolts/Studs/Nuts:

BLOXSPORT Bolts/Studs/Nuts have been specially treated against RUST and thus beautiful and corrosion resistant(Normally 6 Years). Passed the TUV 192 Hours NSS Test.
