Some factory said their wheel bolts are high-strength bolts, the mechanical performance is up to grade 10.9. Actually, the judgment based on material, hardness , Tensile testing, Torque testing and Anti-fatigue testing.
Our wheel bolts are really reach 10.9 grade. We promise the hardness of wheel bolts reach grade 10.9 while the tensile, torque and anti-fatigue also need to reach grade 10.9.  And material we used for bolts are vanadium steel instead of 40Cr. the truly grade 10.9 bolts will not break no matter how hard you bend.
