Full-threaded hexagonal bolts or screws, as the name implies, are that the head of the bolt is a hexagonal head, and the shank of the bolt is all a threaded hexagonal bolt.

Method of measuring the length of bolts:

The length of an external hexagon bolt refers to its thread length. The specific measurement method is to measure the thread length with a caliper (or a micrometer). The measured length is the length of the external hexagon bolt. This length does not include the length of the head, only the length of the thread of the hexagonal bolt needs to be measured. For example, the length of the bolts that do not include the head is more. For example, the length of the pan-head bolt, the inner hexagonal bolt, and the outer hexagonal bolt do not include the length of the head. However, the length of some bolts includes the length of the head, such as countersunk bolts.
