Abstract
Description
technical field
[0001] The invention relates to the technical field of hardware fasteners, in particular to a fully threaded screw structure with a female hole formed at the tail end. Background technique
[0002] Generally, traditional screws and other fasteners mainly use the threads of the rod and the head body of the tail to achieve unidirectional tightening and parallel fastening. Therefore, according to the inherent characteristics of these fasteners, we know the connection The method is unidirectional, and if the secondary pairing or secondary connection of the tail is to be realized, it is difficult to achieve it structurally. If the secondary pairing of the fastener tail is really necessary, the original fastener must be drilled. Processing or bar welding operations; in this way, it is inconvenient and the work efficiency is relatively low in the actual production line operation. Contents of the invention
