• Rustproof: A-grade TC4 titanium alloy material, corrosion-resistant, no rust.
• Level 10.9: Equivalent to 10.9 grade steel screws. (Only for TC4 material products)
• Vacuum nitriding & Anodizing: Using "Vacuum nitriding" or "anodizing" coloring process, the color is gorgeous and not easy to change color

Power:his product is made of high-quality A-grade titanium alloy material, which is corrosion-resistant and high-strength. Processing is difficult and expensive. It is mostly used in the aerospace field, or international events such as F1 and motorcycle GP.

Pure titanium: low strength and low price. It is suitable for equipment that does not require strength and only meets anti-corrosion requirements
Recovery/secondary smelting titanium: inferior quality, low price. There is no security.

Light: Steel  Titanium Aluminum* Under the same specifications, the weight is about half of that of steel screws, close to that of aluminum screws 

The screw head is forged by "65o degree" high temperature. And specially customized S-PARTS exclusive Logo stamping die. Each mold is used no more than 3oo times to ensure the accuracy and strength of the tool groove.Use a Number 5 hexagon bar wrench
