Blade Bolt

Blade bolts, as key fasteners connecting core operating components such as machine tool blades, excavator bucket teeth, and lawn mowers, are designed specifically to cope with extreme and harsh working conditions. In terms of material and structure, it mostly uses high-strength alloy steel and undergoes precision heat treatment, which combines ultra-high hardness and excellent toughness, and can effectively resist high-frequency impact and axial stress; At the same time, for high-speed rotating equipment, special anti loosening designs such as left-hand threads (reverse teeth), conical fasteni...

刀片螺栓	Blade Bolt	40cr/35crmo	M14, M16, M18, M20, M22, M24, 3/4", 7/8" and Other	ISO9001 / IATF16949	Blade bolts, as key fasteners connecting core operating components such as machine tool blades, excavator Bucket teeth, and lawn mowers, are designed specifically to cope with extreme and harsh working conditions. In terms of material and structure, it mostly uses high-strength alloy steel and undergoes precision heat treatment, which combines ultra-high hardness and excellent toughness, and can effectively resist high-frequency impact and axial stress; At the same time, for high-speed rotating equipment, special anti loosening designs such as left-hand threads (reverse teeth), conical fastening, or reverse limited cavities are often used to ensure self-locking under severe vibration and prevent loosening and flying off. In addition, the surface of the blade bolt is often coated with Dacromet, zinc nickel alloy or wear-resistant polymer, greatly improving its corrosion resistance and wear resistance. With precise thread and cone groove structure, it achieves rapid assembly under low torque and precise control of pre tightening force, which is a solid foundation for ensuring the safe and efficient operation of heavy equipment.

English name	Surface Treatment	level	Application Domain	Product Features
Blade bolt	Black	10.9/12.9	Machinery, Chemical Industry, Environmental, Excavator, Bulldozer	The blade bolt, as a key fastener connecting the core operating components, has the impact toughness brought by high-strength alloy steel material and precision heat treatment process. It adopts special anti loosening structures such as left-hand threads and conical surface fastening to ensure that it does not loosen under extreme working conditions; The surface is treated with coatings such as Dacromet and zinc nickel alloy, which have excellent corrosion and wear resistance; By optimizing the thread and taper groove design, precise pre tightening and rapid assembly are achieved, and strict strength standards are met to ensure long-term stable operation of the equipment in heavy load and high-frequency vibration environments, while also ensuring safety and efficient maintenance.
