承載能力降低的內六角平圓頭螺釘，材料為鋼與不鏽鋼，公制粗牙螺紋，產品等級A；低矮拱形頭部不帶凸緣，不同於 ISO 7380-2。螺釘由嵌入低矮拱形頭部凹孔中的六角扳手轉動，頭部不沉入零件，而是貼在零件表面上：零件既不需要柱形沉孔，也不需要錐形沉孔，圓滑的頂面也沒有會勾住手或電纜的稜邊；太薄而無法加工沉孔的蓋板、護罩、面板與支架都這樣固定。一個規格就是 d × l 組合：螺紋直徑決定頭部直徑dk、頭部高度k、六角對邊尺寸s與扳手嵌入深度t，而長度決定螺釘是保留光桿還是螺紋一直到頭部，並隨之決定頭下圓角半徑——全螺紋螺釘的這一半徑較大。頭部比同一螺紋的內六角圓柱頭螺釘更寬，高度約為其一半——M6的頭部直徑10,5 mm、高3,3 mm，扳手為4 mm而非5 mm——正是把凹孔沉入如此低矮的頭部，限制了螺釘所能承受的載荷：某一規格的最小拉力載荷為同一螺紋、同一性能等級的全承載螺釘的80 %，標記中以性能等級前加0來表示，例如010.9。參考螺紋長度b在M12及以下為2d + 12 mm，M16為3d，這是2022年為使部分螺紋的M16螺釘仍可做拉力試驗而加長的。涵蓋M3至M16的螺紋，公稱長度6至90 mm。頭下帶凸緣的型式為ISO 7380-2。
