There are a variety of different bolts that are used for a variety of different purposes. These include U-bolts, metric bolts, flange bolts and anchor bolts. Each of these bolts has its own specific characteristics, but there are also certain markings that you will find on many of them. You will want to know these markings if you’re looking to purchase a set of bolts or are in the market for new ones.
Anchor bolts
Anchor bolts are metal fasteners that provide a secure connection to the concrete of a structure. They are available in a variety of materials, finishes, and sizes. These are used for both residential and commercial applications.
Anchor bolts are available in sizes ranging from 1/4″ to 4 inches. The anchors are designed to transfer both tension and shear loads. Depending on the type of anchor, they can be drilled into the concrete, or they can be cast in place.
Anchor Bolts are manufactured in the United States. They are tested and meet many industry standards. These include ANSI, FDA, CSA, and DOT. There are two types of bolts – straight and bent. Bent anchor bolts have a bottom portion that creates resistance while the top part is threaded.
Flange bolts
The flange bolt is a kind of fastener that is used to attach flanges together. It is also used in the construction of ships, oil rigs and manufacturing plants. These flange bolts are available in a wide variety of sizes and materials. They are made to withstand high pressure and allow the users to achieve reliable connections.
Flange bolts are one of two components that hold a flange together. They are standardized by several organizations, including the American Society of Mechanical Engineers (ASME) and the MSS. Depending on the flange type and the pressure rating of the flange, they are classified as either non-serrated or serrated. Serrated bolts have teeth to grip surfaces and prevent them from slipping. Non-serrated bolts do not have teeth.
U-bolts
U-bolts are metal bolts that come in a variety of sizes. These can be used to secure pipes, cables, and other items. They are typically made from steel or alloy steel. Some u-bolts are coated with a rubber coating to absorb friction and reduce vibration.
U-Bolts are commonly used as support mechanisms for pipework, especially in the plumbing industry. When properly installed, these can provide extra rigidity to a system.
The curved shape of these bolts allows them to fit around pipes, providing a tight connection. These bolts are generally fastened with nuts for a firm hold. They can also be plated with zinc to increase corrosion resistance.
Stainless steel is another common material for U-bolts. This type of metal is highly resistant to rust and can be hot-dipped for added protection. It is also known for its heat and chemical resistance.
Metric bolts
Metric and US bolts are two types of fasteners that can be used to attach different components together. Both bolts are made from steel and come in a wide range of finishes, from zinc to phosphate. However, there are some differences that you should know about.
One important difference between the two types is the thread pitch. The pitch is the distance between the apex of the adjacent threads on the shank of a bolt. There are up to four options to choose from. A fine thread bolt has a higher thread pitch. This means it has more distance between the threads.
Another important factor in determining which bolts are the best is the material. Stainless steel, zinc and alloys are common. You can also check the colour. Most bolts are coated with a zinc finish for corrosion resistance.
Common markings
The markings on US bolts vary depending on the type of bolt and manufacturer. Some of the most common types of markings are letters, dashes, numbers and slashes. These markings can help you to determine which bolt is best for your project.
Standard fasteners, such as those for industrial and mechanical applications, are regulated by SAE standards. These standards are divided into classes. Grades are assigned to fasteners, based on their tensile strength.
In addition to class and grade identifiers, manufacturers also mark bolt heads. Aside from the standard identification marking, many nuts and bolts carry an indent, which indicates the strength of the fastener. Typical fastener standards cover dimensional tolerances, plating, material composition, and other important aspects of the product.
