Measurement of the half angle error of the thread gauge

The thread gauge half-angle error Δα/2 refers to the difference between the actual tooth half angle α'/2 and the basic tooth half angle α/2, that is, Δα/2=α'/2-α/2 has the tooth half angle error, Interference occurs on the flank to affect the screw-in property, affecting the contact area between the flank, and reducing the joint strength. Therefore, the half-angle error of the thread gauge must be controlled. In the actual measurement, in order to eliminate the non-parallel caused by the axis of the thread gauge and the longitudinal guide of the instrument.

Alloy 5083 aluminum plates have higher strength than 5052 plate and has exceptional thermal conductivity. In the tempered condition, it retains good formability due to excellent ductility. It is highly suitable for welding and can be hardened by cold work. Because Alloy 5083 exhibits excellent resistance to general corrosion, it is used in marine applications. Since Alloy 5083 is capable of withstanding extremely low temperatures without brittleness or loss of properties, it is especially suited to the cryogenic market.Superior corrosion resistance, good weldability, with excellent formability, makes 5052 Aluminum Sheet a common choice for chemical, marine or saltwater applications. 5052 Aluminum Sheet applications include: tanks, marine hardware, boat hulls, etc.
