Stainless Steel Coach Bolts: Uses and Benefits


Coach bolts also referred to as carriage bolts, are used for attaching wood to metal. They are mainly used in woodworking and carpentry. 

The bolts feature a domed head and a smooth shank. The head shape is hexagonal, square, or circular. Underneath the head, there is a square nut that allows the bolt to self-lock. 

Coach bolts are made from different materials. The most popular of these materials are stainless steel and zinc.  

Uses of Stainless Steel Coach Colts

Stainless steel coach bolts are used for fastening timber together or wood to metal. They are mainly used in situations where extreme fastening is required. They are quite sturdy, and they are resistant to rust and corrosion.

It is worth mentioning that the steel used for making coach bolts is mild steel, which has high tensile strength and impact strength. In cases where tensile strength is vital, they may not be ideal because mild steel has a strength limit. In such cases, hardened steel would be the ideal option because they are more tensile strength than mild steel. 

Coach bolts are ideal for outdoor projects because they are coated to help prevent rusting and corrosion. If you use coach bolts that are not coated for outdoor projects, the chances are that they will rust quickly. Fortunately, most of them have a coating to prevent rust and corrosion.
