Blade Bolts

Premium Blade Bolts for Lawn Mowers, Rotary Cutters, and More.

Blade bolts are high-strength fastening components designed to secure blades to the hub or rotor in wind turbines, gas turbines, steam turbines, and other rotating machinery. As critical safety parts, they must withstand extreme centrifugal forces, vibration, and harsh environmental conditions. Manufactured with precision from premium alloy steels, stainless steels, or nickel-based alloys, blade bolts ensure reliable and long-term performance in demanding applications.

Crafted with precision, our blade bolts meet stringent industry standards or client-specific requirements.

Key Features of Blade Bolts

High Strength & Durability – Designed to endure heavy loads and high rotational stresses.
Fatigue Resistance – Special heat treatment and surface finishing to prevent failure under cyclic stress.
Corrosion & Temperature Resistance – Suitable for offshore wind turbines, high-temperature gas turbines, and humid environments.
Precision Engineering – Strict dimensional tolerances and controlled preload guarantee secure and stable connections.
Custom Solutions – Available in multiple sizes, thread types, coatings, and materials to meet project-specific requirements.
