U Bolt Square Non Standard Internal Threaded Anti Sway Aluminum Fastener

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 the pipe it was supporting. U bolts are also used to hold ropes together. Ever Hardware provides custom-made fasteners and customizable packaging.
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:
Material type (for example bright zinc-plated mild steel)
Thread dimensions (for example M12 * 50 mm)
Inside diameter (for example 50 mm – the distance between the legs)
Inside height (for example 120 mm)

Aluminum is a relatively soft, durable, lightweight, ductile, and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. It is nonmagnetic and does not easily ignite. A fresh film of aluminum serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far-infrared radiation. The yield strength of pure aluminum is 7–11 Mpa, while aluminum alloys have yield strengths ranging from 200 Mpa to 600 Mpa. Aluminum has about one-third the density and stiffness of steel. It is easily machined, cast, drawn, and extruded.
