ISO 7380-2
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) 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)
吊環螺絲
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）。
十字或米字孔亦可接單生產
a) This bolt features an external hexalobular socket with a small flange, and is designed for applications requiring a high torque transfer with reduced risk of cam-out.
b) The star-shaped head allows for great torque transfer by distributing the load more evenly across the drive, compared to traditional drive systems like Phillips, Pozi or slotted.
a) A ribbed neck screw is a type of fastener designed with a special feature on its shank or neck. Instead of a smooth or threaded surface, the neck of the screw has ribbed, serrated, or knurled features. These ribs or serrations provide additional grip and resistance when the screw is driven into a material, preventing it from rotating or loosening.
