Falling under the group of simple machines, zinc carriage bolts and nuts are used to fasten parts snugly and securely. They are referred to as simple machines because they are devices that are devoid of any moving parts. While they don’t have moving parts, they overcome resistance and increase the amount of force that is exerted.

The carriage bolts are part of the screw family. They have another name in other countries and they can be called coach bolts or plow bolts. At its most basic, screws are simple machines that prescription cialis generic work with a cylinder and a flattened top. A head is found on the other end that allows it to be turned and the cylindrical end of the screw can be threaded either fully or partially.

The head of all carriage bolts are dome shaped. Technically, these zinc carriage bolts have countersunk heads which are not meant to be driven like regular screws. It is characteristic for the shank being topped with a short square segment. At the end of the bolt, a nut is fastened in place to enhance the strength in the hold that is putting the things together. The nut basically locks the carriage bolt in its place. Holes on the parts to be assembled are pre-drilled, the short square section underneath the head grips onto the part being put together to keep the bolt from turning or twisting when the nut is being tightened in a lock. From metal applications, zinc carriage bolts have ribbings that take the place of the square underneath the head of the bolt.

Zinc carriage bolts are essentially the tools you need to put wood pieces together. Wood to metal applications is also possible though. In a sense, the square under the head boars into the wood as the nut is set in place for a tighter fit. The ribbing does the same thing but it’s better for putting wood and metal parts together. For construction projects that regularly face the elements like in decks, docks, or swing sets, carriage bolts are the ideal bolt to use. The steel that makes up the bolt is plated with zinc in zinc carriage bolts to provide moderate protection from corrosion and rusting.

For whatever kind of project, a variety of diameters can be used with regard to carriage bolts. It can range from 3/16 to 1/2. The correct width, diameter, and length of the bolt has to be used when constructing pieces or projects. Too big and it puts pressure on the wood or metal that cracks or breaks it. Too small and the bolt itself might break. Carriage bolts are usually used to put thick pieces of wood together. A short bolt won’t go through the materials and a longer one protrudes causing an unfinished look in the construction and it also might become a hazard. For putting pieces together, be it wood to wood or wood to metal application, zinc carriage bolts do the job as a simple machine.
