The principle when tightening the foot loop screws is: the tighter you tighten them, the better they prevent the foot loop from twisting or untwisting - the engineer calls this "force-fit". In the case of the loops, however, the problem is that you are turning self-tapping screws into a comparatively soft plastic plug. If you apply too much force, you quickly overtighten the plug and render it unusable. If, on the other hand, you don't tighten the screw enough, the friction of the foot loops on the footpad is too low - the loops twist, the screws work, which again damages the plug in the long term.
Developer Guido Hennen, who works full-time as an engineer, has therefore developed the S4lt ATW 277, which is designed to "decouple" the forces that occur.
Firstly, unscrew the foot loop screws and remove the plastic or metal plates on the loops that are usually installed on standard boards. Then you have to make sure which plug spacing is available on your own board - the one with around 13 millimetres or the wider spacing of just under 25 millimetres. In the case of the narrow spacing (13 mm), the thinner grub screws are used, whereas for plugs with 25 millimetre spacing, the screws with a large head are used as anti-rotation screws. In both cases, the anti-rotation screw is inserted into the respective neighbouring plug so that it protrudes a few millimetres at the top.
If you now turn the screw into the plug, you can do so in the knowledge that you no longer have to tighten it fully - twisting of the foot loop is now successfully prevented by the anti-twist screw, not by tightening it.
It is still theoretically possible to tear out the plugs or tear off the screw with the S4lt ATW - after all, the foot loop is still attached with just one screw. However, the main cause of damage to the plug or screw - the need to (over)tighten the screw - is successfully eliminated with the system. You should also tighten the screws properly with the ATW, as the deeper they are screwed in, the better they hold in the plug. The system is particularly useful on boards where the standard anti-twist protection of the loops no longer works properly.
