DRAWING-LED FASTENERS
Wind Turbine Blade Root Studs
Double-ended studs for wind turbine blade root connections. Supplied as individual studs or with specified barrel nuts and outer nuts for a T-bolt connection.
SPECIFICATIONS & CUSTOMIZATION
Define The Geometry.
Define both threaded ends, the shank profile and the mating barrel nut as one coordinated connection.
Dimensions & Configuration
- Thread Diameter · d
- Thread diameter and pitch at each end to the blade-root drawing
- Overall Length · L
- End-to-end stud length, including both threaded sections
- Threaded Ends · b₁ / b₂
- Specify the engagement length at each end separately
- Shank Diameter · ds

Material & Mechanical Requirements
42CrMo alloy steel and class 10.9 are project options. Specify the material, mechanical properties and any required fatigue test criteria for the stud and matched barrel nut.
Threads & Connection
Specify the thread form, pitch, tolerance and both engagement lengths. Match the stud to the barrel nut and the outer nut on the blade-root connection drawing.
Surface & Protection
Zinc-flake coating or another specified protective system. Define coating, friction requirements and thread protection together with the tightening specification.
COMPONENTS & INSPECTION
Coordinate The Stud And Its Barrel Nut.
Supply Configuration
Specify whether the order covers studs alone or a matched T-bolt connection set.
