名稱
十字槽沉頭螺釘 |
英文名
Countersunk flat head screws |
替代標準
GB819

材料
不銹鋼 鋼 |
表面
本色,鈍化,電鍍... |
性能等級
A2-50 A2-70 4.8 |
特點
持平于基材 |
與GB819一樣,DIN965沉頭螺釘可以嵌入工件表面,不會突出或凸出,使得工件表面更加平整美觀后發生塑性變形的作用。尺寸方面DIN965也幾乎接近于GB819(但還有有些差異的)。

備注 | 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. |
