1. PP+TPR and multiple materials handle, with ergonomic design could remove screw fast, smooth hard area can be quickly sliding on the hand, soft grip area can transfer greater torque
2. Rubber coating with micro-fine surface structure, increase friction
3. The head of blacken rod part use precision machining to match with screw perfectly, it has best corrosion resistance
4. The rod part with vacuum heat treatment,which is initiated in China, the comprehensive performance is 6.5 times higher than ordinary heat treatment
5. Hexagonal rod part + one-piece hex bolt design, through allen wrench or cocket wrench to screw the hex bolt, gives maximum torque transmission
6. S2 material hardness HRC ≥ 59. The torque exceeds the German standard,S2 is over 70%.
