The semicircular head square neck bolt is also called a carriage bolt. It has a semicircular head and a square neck. The carriage bolt has a good fixing effect, and the square neck just fits the bolt to facilitate the tightening of the nut. It also has a good anti-theft effect because the head is semicircular and has no grooves. It can be used to connect iron and wood structures, such as cars, textile machines, flour machines, lifeboats, etc.
