Hot dip galvanized bolts are classified into general hot dip galvanized bolts and hot dip galvanized bolts with reamed holes.
Hot-dip galvanized bolts have external threads and screwcaps that can be fused together on either side. The key is to fix the immobile tubular material or block, which is called a mounted horse bolt because of the way it fixes immobile objects like a man riding on them at once.
