In addition, to meet the needs of the lock after installation, there is a hole in the head, rod section with holes, these holes can be loose when the bolt is not subject to vibration.
Some did not bolt threaded rod to painstaking, called slender bolts. Bolts favor of this change by force coupling.
There are special high strength bolts on the steel. Head will become bigger and more. Dimensions have changed.
Another special use of: T-shaped slot bolts, jigs and fixtures used in the most special shape, the sides of the head to cut off the bolt, and ground connections for machine fixed, there are a variety of shapes U-shaped. bolt, as described above. Like.
