A spiral shaped continuous raised part having a specified cross section on the surface of a cylinder or cone. According to its parent thread shape is divided into cylindrical and conical screw threads; according to their position in the matrix is divided into outer and inner thread, according to the section shape (teeth) divided into triangular thread, rectangular screw, trapezoidal thread, serrated thread and other special shape screw.
M6 need to drill 4.8mm hole thread. Calculation method:Generally, the diameter of the Gong bolt multiplied by 0.86 is the diameter of the hole to be drilled.M6 thread refers to the nominal diameter of 6mm coarse teeth, ordinary thread.
M6 is generally 4.8 of the bottom, but I do find it hard to die when the attack!! So basically use 5 or 5.2!
