Hot Dip Galvanized Carbon Steel Carriage Bolt

Carriage Bolts, also called round head square neck bolts, generally feature a broad, shallow round head and are inserted into pre-drilled holes. The square neck under the head keeps the carriage bolt from turning as the nut is tightened. Carriage bolts are commonly used to fasten wood or wood and metal parts together.

Our carriage bolts with nuts are standard round head bolts with square necks and unified thread pitch carriage bolts. Made from low or medium-carbon steel (AISI 1006-1050 or equivalent steel) with a zinc finish. 

Application

Carriage bolts are ideal for fastening wood to metal. Alternatively, carriage bolts can also be used to fasten two pieces of wood together. Some specialty versions of carriage bolts allow for the effective fastening of two separate metal components. Furthermore, they can be used in a variety of different industries including the following:

Water conservation and treatment industry,

Railroad industry,

Farming industry, and

Mining industry, to name a few.

Finish

Hot-dip galvanizing is a process in which metals such as steel, stainless steel, and cast iron are immersed in molten zinc liquid or zinc alloy to obtain a metal coating. The main purpose of this method is to enhance the anti-corrosion properties of steel by plating a layer of zinc alloy on the surface of steel products, thereby extending its service life.
