a) DIN 912 (ISO 4762) 是指公制內六角螺絲的特定標準, 也稱為杯頭螺絲, 具有圓柱形頭部, 中心有六角形凹槽 (Socket), 可以使用內六角扳手 (Hex Key or Allen Wrench) 將其旋緊或鬆開. 這些螺絲通常用於需要高拉伸強度的各種應用。
b) 帶滾花頭的內六角螺絲是 DIN 912 的變化型,頭部周圍具有滾花紋理表面。這種設計提供了更好的抓握力,便於手動操作或調整,特別適用於需要頻繁調整的應用場合。
a) ISO 7380-2 訂定了帶有華司的內六角圓頭螺絲標準。通用內六角梅花孔(6 lobe)設計是另一種在各種應用中廣泛使用的常見替代方案。
b) 此螺絲在牙尾末端有一個延伸的圓柱形尖端( 通稱為狗尾 dog point), 其作用為可在對接的部件中做到精確地對準與定位。
a) DIN 7500 specifies self-tapping screws for metal, also known as thread-forming screws. These screws are designed to form or cut threads in a pre-drilled hole in metal materials, without requiring a pre-cut thread.
b) The screw shank has a three-lobe shape instead of a round cross-section, which reduces friction during installation, and facilitates smooth material displacement and efficient thread formation.
c) The long dog point (the extended, unthreaded tip of the screw) acts as a pilot, helping to align the screw with the pre-drilled hole during installation, and faciliates smooth installation.
d) A standard trilobe thread forming screw without dog point is avaialble upon request.
a) 鑽尾螺絲是一種設計用於在旋入過程中自動鑽孔並切割螺紋的螺絲,無需預先鑽孔。它具有類似鑽頭的尖端,能夠輕鬆穿透工件。這種設計有助於加快安裝過程並提高效率。鑽尾的形狀和材質會影響螺絲的鑽孔能力,從而決定在不同材料中的表現。
b) 頭部下方的鋸齒狀設計會在螺絲頭部與材質之間產生額外的摩擦,幫助防止螺絲鬆動。鋸齒狀表面為螺絲起子等工具提供更好的抓握力,使得在安裝過程中可以施加更大的扭矩,從而提高螺絲的固定效果。
