根据需要固定的光孔直径,例如,光孔直径为11mm,可以选择螺栓,M10,该尺寸比其小一号。 至于长度,它取决于紧固件的厚度和所需的螺母厚度。 通常,将这些厚度加在一起,然后再增加5mm。 通常,拧紧螺栓后螺母可以看到螺栓的末端为2?3mm。
According to the fixed light hole diameter, for example, if the light hole diameter is 11mm, bolt, M10, which is one size smaller than it, can be selected. As for the length, it depends on the thickness of the fastener and the required nut thickness. Usually, these thicknesses are added together and then increased by 5 mm. Generally, the end of the bolt can be seen to be 2? 3mm after tightening the bolt.
