Hexagon nuts (20 sheets) For hexagon nuts, the commonly used standards are: GB52, GB6170, GB6172 and DIN934.

In the M8 nut series, the opposite sides of DIN934, GB6170 and GB6172 are 13MM which is 1MM smaller than the 14MM of GB52. For the M10 nut, the opposite side of DIN934 and GB52 is 17MM, The opposite side of GB6170 and GB6172 is 1MM larger. For M12 nuts, the opposite side of DIN934 and GB52 is 19MM than the opposite side of GB6170 and GB6172 18MM is 1MM larger. For M14 nuts, the opposite side of DIN934 and GB52 is 22MM, which is 1MM larger than the opposite side of GB6170 and GB6172, 21MM. The other is the M22 nut. The opposite side of DIN934 and GB52 is 32MM, which is 2MM smaller than the 34MM opposite of GB6170 and GB6172. (GB6170 and GB6172 have the same width on opposite sides except for their different thicknesses) The other specifications can be used universally without considering the thickness.
