Hub Bolt

　　Characteristics of wheel hub bolts:

　　◆ High strength and reliability

　　High quality materials: Made of high-strength alloy steel (such as 10.9 grade, 12.9 grade) or stainless steel, which undergoes heat treatment (quenching, tempering) to enhance tensile strength and hardness, ensuring the ability to withstand dynamic wheel loads.

　　Fatigue resistance: treated with special technology, able to withstand long-term vibration, impact, and alternating stress, avoiding fracture or deformation.

　　◆ Accurate matching and compatibility

　　Standardized threads: strictly comply with international standards (such as metric M12 × 1.5, imperial 1/2 "-20, etc.) to ensure perfect fit with the wheel hub and bearing seat.

　　Length and taper adaptation: Multiple specifications (such as taper 10 °, spherical 13 °) are suitable for different wheel hub designs to avoid installation interference or looseness.

　　◆ Anti loosening and safety design

　　Flange or serrated design: increases the friction force of the contact surface to prevent nut loosening during driving.

　　Pre coated anti loosening adhesive: Some bolt threads are pre coated with nylon adhesive to enhance the locking effect.

　　◆ Corrosion resistance and long lifespan

　　Surface treatment: Galvanized, Dacromet, phosphated or stainless steel materials, resistant to rainwater, snowmelt salts and acid alkali corrosion.

　　Antioxidant coating: suitable for harsh environments such as coastal areas and winter roads.

　　◆ Convenient installation and maintenance

　　Tool friendly: Standard hexagonal head (such as 17mm, 19mm) or inner plum blossom design, suitable for universal wrenches or torque tools.

　　Guided end design: Some bolts come with guide cones for quick alignment and installation.

　　◆ Anti theft and personalization

　　Anti theft bolt: Special pattern or key disassembly design to prevent wheel hub theft.

　　Appearance customization: Provides black, blue and other coatings to meet the aesthetic needs of modified cars.

　　◆ Strict quality control and certification

　　Industry certification: Tested according to ISO, DIN, JIS and other standards, some high-end brands provide T Ü V certification.

　　Accurate torque: Clearly label the installation torque value to ensure safe tightening (such as 90-120N · m).
