Vòng đệm khóa nêm nhiều kích thước, hiệu HEICO
An important feature of HEICO-LOCK® wedge locking washers, setting them apart from other systems that are available, is the securing of the bolt fastening using preload force rather than friction
- Wedge-shaped surface on the inside of the lock washers, radial teeth on the outside;
- Interlocking embedding of the radial teeth with the respective mating surface (when the bolt is tightened);
- System movement only possible between the inside washer surfaces, the securing system to readjust itself automatically;
- Increase in clamping force.
