The "Six-Claw Speed Washer" is an easy-to-install, screw-specific anti-loosening washer that can secure components simply by pushing it onto a bolt. The claws bite into the screw threads and cannot be removed from the opposite direction. Since there is no need to turn it like a nut, it is expected to reduce installation time. Additionally, by improving the shape of the claws, it has become possible to insert it with about 50% of the force required for conventional models, while maintaining the same anti-loosening capability. 【Features】 ■ Easy installation ■ Suitable for mounting insulation and soundproofing materials ■ No need to turn it like a nut ■ Expected reduction in installation time ■ Improved claw shape *For more details, please refer to the PDF materials or feel free to contact us.

The "Speed Nut" is a product that can be secured simply by pushing it in, rather than twisting it like a regular nut. It has angled claws in the inner diameter that bite into the main shaft, and due to the spring action, it holds the opposing shaft in place, making it impossible to pull out from the opposite direction. Since it can be secured just by pushing, it is effective for speeding up installation. We also offer a "Screw-Type Speed Nut." 【Features】 ■ It has a structure that holds the opposing shaft in place due to spring action, preventing it from being pulled out from the opposite direction. ■ It is effective for speeding up installation since it can be secured just by pushing. ■ Suitable for the installation of interior components. ■ Using the Speed Nut reduces work time and cuts costs. ■ Made of stainless steel, it has high strength and excellent corrosion and heat resistance. *For more details, please refer to the PDF document or feel free to contact us.
