- Preload systems
The solution developed and patented by TSF is intended to improve the safety on exposed elements as public furniture, solar panels, vehicle wheels, access doors, electric panels and a long list of applications.
As an added value in comparison with other solutions, the TSF security screw has the possibility of being reusable, given that during the assembling, the integrity of the screw is not affected. This is possible thanks to the specific design, featuring six sectors with inclined surfaces that allow to use two different tools for tightening and untightening.
Due to the use of the six sectors design, it is also possible to customize configurations for diverse customers and create a unique screw for each of them.
