1.Where is the hexagon bolt used?
Hexagon bolts are widely used indoors and outdoors, especially in building installation, bridges and roads, power facilities, etc. Mechanical equipment, medical devices and electronic instruments are widely used indoors.
2.What’s the difference between full-tooth external hexagon bolts and half-tooth external hexagon bolts?
The difference between half-toothed hexagon bolts and full-toothed bolts is that some screws of half-toothed bolts are polished rods without threads, so they are called half-toothed hexagon bolts. Both generally need to be used with nuts.
3.Difference between coarse thread and fine thread of hexagonal bolt
The pitch of fine thread is small. On the same thread length, more threads are screwed in, which is more conducive to the self-locking of the thread. Therefore, fine thread is generally used in places that need to prevent loosening.
4.Difference between external hexagon head bolt and internal hexagon head bolt
The screw head of the internal hexagon head bolt is round on the outside and hexagonal in the middle, while the external hexagon head bolt is the kind of hexagon head bolt with hexagonal sides that we usually see.
