Eight common misunderstandings of fastener pins
1. Use coarse teeth instead of fine teeth
There are many important connecting parts on the machine, such as drive shafts, etc. Most of the bolts are fine thread. If there are missing parts during maintenance, some maintenance personnel will use coarse-toothed bolts instead, which should be avoided. Because the inner diameter of the fine thread bolt is larger, the pitch and outer angle are smaller, the strength is high, the self-locking performance is good, and the ability to withstand shock, vibration and exchange loads is also relatively strong. Once the coarse-toothed bolts are used instead, it is easy to loosen or fall off, dismantle, and even cause mechanical accidents.
