What kind of threads are used in Torx bolts?
Thread-forming screws press threads into drilled holes for a tight vibration-resistant assembly. Threads change direction to cut into composites and push material back into the hole to prevent distorting the surface around the hole. These steel screws have a black-oxide or zinc-plated finish to resist corrosion.

Is there a way to check the torque of a bolt?
Bolt torque can be checked with a tool such as a torque wrench, but without a value as a guideline, a torque wrench offers no advantage. To arrive at the correct torque value, several other values must be found first. Two principles influence the correct clamping pressure for each bolt, known as clamp load.
