Flexible nut combinations to match your specific assembly and vibration resistance requirements.
Plain hex nuts providing basic fastening. Suitable for static applications or where vibration is minimal. Most economical option for standard installations.
Nuts with integral washer providing increased bearing surface. Ideal for applications with delicate surfaces or where load distribution is required.
Self-locking nuts with nylon insert preventing vibration loosening. Recommended for dynamic applications and machinery subject to continuous vibration and movement.
Purpose-built for demanding agricultural and industrial cutting machinery applications.
Blade bolts for combine harvesters, forage choppers, and hay balers where cutting blades experience extreme loads and impact forces.
Precision fastening for blade assemblies in rotary cutters, brush mowers, and industrial shredders operating at high RPM.
Critical fasteners for wood chippers, log splitters, and sawmill equipment where cutting forces are severe and unpredictable.
Blade bolts for excavator buckets, trenching equipment, and soil preparation machinery requiring extreme holding strength.
41Cr4 alloy composition provides exceptional fatigue strength and vibration damping for continuous-duty applications.
