  How to find good screw manufacturers?     I don’t know what you are defining good  screw manufacturers . Is it to look at their prices? Still, look at their quality? Still, look at their delivery dates? In my heart, a good screw manufacturer needs to have many conditions.   ★Quality.

  Why is the binding head tapping screw easy to break? Some customers bought the  binding head tapping screw  and used them back. They found that the screws are always easy to break. Why is this? The  binding head tapping screw  is easy to break, there are several reasons: ——The torque is too large. Use the torque of this screw to tighten the screw, so the screw will break. ——In addition to hydrogen is not complete. When the binding head tapping screws are made of carbon steel, the hydrogen is not completely removed, and it will be brittle when used, which is what we call hydrogen embrittlement. ——Not the strength level we require. For example, we require a 12.9-stage  binding head tapping screw , but in fact, it is a 10.9-class screw. When we use it, we use the corresponding torque of 12.9 to use the screw, and the screw will also break. ——The thread bottom diameter is too small.
