What is fin neck bolt?
A fin neck bolt, also known as a silo bolt, is a specially designed bolt with a round head and neck with four fin pieces. Similar to a carriage bolt, the head of this bolt does not have a drive structure, but instead fits into the connector through the fin neck of the neck, preventing the screw from rotating. This means that it can only be tightened from the nut part.
