螺钉:内六角平圆头

ISO 7380-1

承载能力降低的内六角平圆头螺钉,材料为钢和不锈钢,米制粗牙螺纹,产品等级A;低矮拱形头部不带法兰,不同于 ISO 7380-2。螺钉由嵌入低矮拱形头部凹孔中的六角扳手拧动,头部不沉入零件,而是贴在零件表面上:零件既不需要柱形沉孔,也不需要锥形沉孔,圆滑的顶面也没有会勾住手或电缆的棱边;太薄而无法加工沉孔的盖板、护罩、面板和支架都这样固定。一个规格就是 d × l 组合:螺纹直径决定头部直径dk、头部高度k、六角对边尺寸s和扳手嵌入深度t,而长度决定螺钉是保留光杆还是螺纹一直到头部,并随之决定头下圆角半径——全螺纹螺钉的这一半径更大。头部比同一螺纹的内六角圆柱头螺钉更宽,高度约为其一半——M6的头部直径10,5 mm、高3,3 mm,扳手为4 mm而不是5 mm——正是把凹孔沉入如此低矮的头部,限制了螺钉能承受的载荷:某一规格的最小拉力载荷为同一螺纹、同一性能等级的全承载螺钉的80 %,标志中以性能等级前加0来表示,例如010.9。参考螺纹长度b在M12及以下为2d + 12 mm,M16为3d,这是2022年为使部分螺纹的M16螺钉仍可做拉力试验而加长的。涵盖M3至M16的螺纹,公称长度6至90 mm。头下带法兰的型式为ISO 7380-2。
