M36 High-Strength Anti-Vibration Bolt and Nut Assembly for Wind Turbine Tower Applications
M36 High-Strength Anti-Vibration Bolt and Nut Assembly for Wind Turbine Tower Applications
Engineered for the bolted joints of wind turbine towers, this M36 Grade 10.9 assembly delivers reliable anti-vibration performance, high fatigue strength, and long-term corrosion protection under continuous dynamic wind loads.
Key Features
-
Proven Anti-Vibration Design — Each set pairs the bolt with a nylon-insert self-locking hex nut (DIN 985 / ISO 10511) and hardened serrated flange washers (DIN 6798), maintaining stable preload under continuous tower vibration and cyclic wind loading.
-
High-Strength Grade 10.9 — Forged from 42CrMo alloy steel, quenched and tempered for high tensile and fatigue strength, with mechanical properties certified per ISO 898-1.
-
Corrosion Resistant, Hydrogen-Embrittlement Controlled — Hot-dip galvanized (HDG) finish with a controlled dehydrogenation baking process suited to Grade 10.9 fasteners; Dacromet coating available as an alternative for offshore wind applications.
-
Matched, Traceable Assembly — Bolt, nut, and washers are supplied as one matched set with traceable batch numbers, and every batch ships with EN 10204 3.1 material certificates to guarantee consistent joint performance.
