A hex cap screw is a cap screw with a hexagonal head, designed to be driven by a wrench (spanner). An ASME B18.2.1 compliant cap screw has somewhat tighter tolerances than a hex bolt for the head height and the shank length. The nature of the tolerance difference allows an ASME B18.2.1 hex cap screw to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex cap screw is designed in.

LED tube light is application of a new type of LED lighting light source on the basis of traditional tube light of the development of improved products, compared with traditional tube light has the following advantages: energy saving, low carbon, long life, good color rendering and fast response.LED tube light, a design more beautiful light, installation to keep building decoration of the overall unity and perfect, does not destroy the set of lamps and lanterns, light hidden inside the building decoration, light source is not exposed, no glare, the visual effect of soft and uniform.
P-n junction terminal voltage constitute a certain potential barrier, when the positive bias voltage drop time base, P and N the majority carrier diffusion to the other party.Due to the electron mobility is much bigger than hole mobility, so there will be a large number of electronic spreading P area, constitute of P area of minority carrier injection.These electrons and valence with hole composite, composite when the energy in the form of light energy to release out.This is the principle of PN junction glow.
