Brass bolts are used to join wood, metal, or composite materials together. There are three major patterns: carriage bolts, stove bolts, and machine bolts. Brass is resistant to rust and corrosion, making it suitable for marine environments and industrial machinery. Brass bolts are also cheaper than stainless steel and solid copper. However, they may not be suitable for supporting high levels of force or weight. Builders must carefully choose the right bolt based on the project’s needs.
A brass bolt is a heavy duty fastener made from an alloy of copper and zinc. Installers use these bolts to join wood, metal, or composite materials together, or to attach objects to surfaces made from one of these materials. A brass bolt is typically held in place by a nut and a washer is used under the bolt head to maximize performance over time.
Installers can choose from three major brass bolt patterns to meet the needs of different applications. The brass carriage bolts have threads along their entire length and a smooth, rounded head. These bolts are chosen primarily for the visual appeal they add to furniture and other wooden items. Holes must be pre-drilled in an object before the carriage bolt can be installed.
Despite the name, a brass stove bolt can be used in a variety of applications. Featuring a slotted head and partially threaded shank, these bolts were originally designed to withstand the high heat and corrosion in a metal stove. Today they can be found on furniture, deck frames, and many metal objects.
Brass machine bolts tend to be larger and stronger than most other brass fasteners. They feature a square head and partially threaded shank and can be found in many heavy duty applications. An additional style of brass bolts that do not use washers or nuts can be installed into some types of masonry surfaces.
Builders often choose brass bolts for their natural advantages over other materials. Unlike steel, brass bolts will not rust or corrode when exposed to moisture or chemicals. For example, a brass bolt can hold much longer in a marine environment than a regular steel fastener. Brass is also less vulnerable to gasoline and other corrosive materials, making it suitable for use in automobiles and industrial machinery.
While stainless steel and solid copper each offer some of the same benefits as brass, they both cost more on average than standard brass. Brass bolts also provide a decorative finish that some users may prefer over steel or chrome. Because brass is not as strong or hard as steel, it may not be suitable for supporting unusually high levels of force or weight.
Each brass bolt must be carefully chosen based on the needs of a particular project. Engineers and builders consider factors such as the length and diameter of the bolt, as well as the type of material it will be installed in. The texture of the shank and the number of threads per inch can also affect strength and durability.
