六角螺栓按螺纹长度可分为全螺纹六角螺栓DIN933(1S04017)和半螺纹六角螺栓DN931(ISO4014)。
DN933六角螺栓相似国家标准号GB5783。DIN933标准适用于螺纹直径为M1.6-M52,产品等级A级和B级的全螺纹六角螺栓。
A级:d≤24mm且L≤10d或≤150mm(按较小値)。B级:>24mm或>10d或L>150mm(按较小值)。不同的产品等级,其相应的对边s、对角e、厚度k以及长度公差数值均有所不同。
一般螺纹直径规格为M3-M64,一般碳钢性能等级主要为8.8级,10.9级。当d≤39mm,可参照lSO898-1;不锈钢通常为A250/A2-70/A4-70/A4-80,当d≤39mm时可参照ISO3506-1或DIN267-11。
表面处理以及螺纹公差:DIN933六角螺栓一般是公制(粗牙)以及细牙,以mm毫米为计量单位。DIN933粗牙螺纹公差6g,涂层主要有发黑、电镀(蓝白锌、黄彩锌),前的公差配合主要为6g6H镀锌后的公差带配合可变为6h/6G,但是涂镀后受表面涂层厚度影响,在进行相应公差的通止规检测螺纹时,也可能会出现无法配合的情况,也只可进行规格相匹配的螺母安装检测。
1SO4017与DN933区别:DN933为德国标准,ISO4017为国际标准。两者在规格M10M12M14M22等在外六角头部对边s、对角e尺寸有所不同,ISO4017尺寸小于DIN933,其他规格差別不大。

备注 | ① Only for screws without surface protection. 6 g makes it possible for normal coating thicknesses to be applied in accordance with DIN 267 part 9, the reference line not being exceeded. Depending on the coating thickness required, a larger fundamental deviation shall be selected than that for the g position. This might, however, impair the resistance to stripping of the bolt / nut assembly. |
