An anchor bolt is used to attach objects or structures to concrete. There are many types of anchor bolts, consisting of designs that are mostly proprietary to the manufacturing companies. All consist of a threaded end, to which a nut and washer can be attached to the external load. Anchor bolts are extensively used on all types of projects, from standard buildings to dams and nuclear power plants. They can also be used to firmly affix embed plates to a concrete foundation when used with a structural steel element.
The simplest anchor bolt is a cast-in-place anchor. As seen in the figure, most designs consist of a standard bolt with a hexagonal head, which is cast in the wet concrete before it sets. There are other designs, some consisting of a bent bolt with a hook on the end or some other sort of bending. Cast-in-place anchor bolts are the strongest type of fastener, but the casting is difficult, and they are usually only used for heavy machines mounted on poured concrete floors. Another use of this anchor bolt is to connect the concrete foundation of a building to its wall. With this, the building is more resistant to earthquakes. Currently, there are several devices to assist in holding and in placing anchor bolt to set in the concrete. These devices are mostly made of composite plastic.
Once the concrete has been poured and set, the only other types of bolts that can be used are mechanical and epoxy bolts. Epoxy bolts are the strongest but can be very tricky to install, since the epoxy has to be mixed to exact specifications, the hole must be very clean, and the set time has to be watched. As well, there must be a rigorous testing program. In Boston's Big Dig project, these procedures were not well carried out, which resulted in a large concrete slab crushing a motorist.
A concrete screw is another way of attaching things to concrete that has already been poured and set.

| Shape | U-shaped |
| Material | SS, MS, CS |
A U-bolt is a bolt in the shape of the letter U with screw threads on both ends.
U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by the size of pipe it was supporting.
For example, a 40 Nominal Bore U-bolt would be asked for by pipework engineers, and only they would know what that meant. In reality, the 40 nominal bore part bears little resemblance to the size and dimensions of the U-bolt.
The nominal bore of a pipe is actually a measurement of the inside diameter of the pipe. Engineers are interested in this because they design a pipe by the amount of fluid/gas it can transport.
As U-bolts are now being used by a much wider audience to clamp any kind of tubing / round bar, then a more convenient measurement system needs to be used.
Four elements uniquely define any U-bolt:

Hex Flange Bolt

Copper rivets and fasteners are often utilized in manufacturing applications due to their strength after cold-heading, corrosion resistance, and antimicrobial properties. We increase the strength of our copper products by the cold forming process, making it an ideal fastener for your requirements.
Due to its decorative appeal, copper is an ideal material for manufacturing functional items, and its conductivity makes it perfect for use in electrical applications. Copper rivets are commonly used in clothes, saddles, shoes, bags and more to reinforce the product and because of how aesthetically pleasing copper rivets look.
