They fit me perfectly. I've never had failures. I have solid oak boards about 3/4" thick. I don't think they work well with thinner floors. I drilled 3/32 holes. I use a variable speed drill bit. I drill at a constant slow speed, until the head touches the guide. Then I quickly switch to high speed by quickly pulling the trigger. This rapid increase in torque almost always causes the propeller to fail. About 5% of the time, the screw spins and nothing breaks. I don't know why this happens, maybe the black floor is damaged in these places.While I mounted 100 screws and bought another 100. The previous owner, in my opinion, had a flood in the hallway, it constantly creaked along the entire length (18 meters) So far this has solved the problem.
