DIN 912 / ISO 4762
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) 此規範定義了 十字孔盤頭螺絲 (Cross recessed raised cheese head screws) 的規格. 這些螺絲具有凸起的圓柱形頭部, 一般常見孔型為 十字孔 type H (Phillips), 米字孔 Type Z (Pozi), 和 梅花孔 (Hexalobular socket / 6 lobe)
與 (DIN 6922) 類似, 這些螺栓在頭部下方也有一個法蘭圈（盤形延伸部分), 可作為整合墊圈之用. 法蘭圈提供了更大的承載表面並有助於分佈負載, 使這些螺栓適合各種應用. 某些六角法蘭螺栓會在頭部下方帶鋸齒, 這進一步強化了它們在不同應用場合上的功能。
a) A stainless steel self-tapping thread for thermoplastics is a type of screw designed specifically to create its own threads when driven into plastic materials.
b) These screws have wider, sharp, and deep threads, which allow them to cut into the softer thermoplastic material efficiently, creating a secure, long-lasting hold.
