A single head bolt is a type of bolt. The surface treatment is galvanized or hot-dip galvanized or stainless steel, and the materials are Q235, 45# steel, SUS304, SUS316, etc. The use of single-head bolts is more flexible than ordinary bolts. It can also be used as a normal bolt after adding a nut to the unthreaded end. A single-head bolt, a type of fastener consisting of a head and a screw (a cylinder with an external thread), is required to be fitted with a nut for fastening two parts with through holes.
This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
