a) DIN 965 制定了具有十字槽孔 (通常稱為 phillips) 的平頭螺絲標準。這些螺絲通常用於需要平坦表面的應用. 平頭型能使螺絲與材料表面齊平, 從而提供整潔的外觀。
b) 十字槽孔與米字槽孔因其易於使用相容螺絲起子安裝和拆卸而被廣泛使用。此外, 另一常見的六角瓣孔(梅花孔)設計亦可提供更好的扭矩傳遞並最大限度地減少螺絲旋入過程中脫出的風險。

a) The screw head features a hexalobular socket, often referred to by the generic name “6 lobe”
b) The flat underside of the pan head distributes clamping force over a larger area compared to countersunk or round head screws.
c) Although there may be minor differences in dimensional tolerances or thread requirements, both DIN 7985 (German standard) and ISO 14583 (international standard) specify pan head screws.
