DIN 968
a) DIN 968 制定了帶華司盤頭十字孔自攻螺絲的標準。這些螺絲通常搭配兩種類型的孔型：H 型（十字槽 phillips）和 Z 型（米字槽 pozidrive), 兩者均設計用於輕鬆安裝和拆卸。
b) DIN 7970 自攻螺絲規範中 亦制定了兩種類型的螺紋尾端：C 型（錐型尾 cone point）和 F 型（平尾 flat point）。

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) A self-tapping screw for thermoplastics is a specialized fastener designed to create its own threads as it is 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.
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) 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.
