FAQ
In a motor, long screws clamp the housing around the stator and rotor. If a screw is bent or lacks concentricity, it applies uneven pressure, causing stator distortion, high-speed vibration, and excessive noise. Our manufacturing process ensures perfect straightness to eliminate these issues.
Yes. We specialize in producing custom extra-long fasteners designed specifically to accommodate the deep internal structures of complex industrial motors and power equipment.
