Product introduction
Countersunk heads are generally used where the surface is required to be smooth after connection because countersunk heads can be screwed into parts. Round heads can also be screwed into parts. The tightening force of square head can be larger, but the size is large. In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rod, which can make the bolt not loose when it is vibrated. Some bolts have no thread of the smooth rod to do fine, called the waist bolt. This kind of bolt is good for coupling under varying forces. There are special high-strength bolts on the steel structure, and the head will be larger and the size will change. In addition, there are special uses: T-groove bolts, the most used on the machine tool fixture, special shape, both sides of the head to cut off. Anchor bolts, used to fasten machines to the ground, come in many shapes. U-bolts, as described above. And so on. There are special studs for welding.
