Bent eye screws

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。

DIN 6922 概述了具有細桿徑的六角法蘭螺栓的尺寸和技術規格. 此螺栓另一特點是有一個法蘭圈, 頭部下方有一個圓盤形延伸部分, 用作整合墊圈. 法蘭圈的加入增強了軸承表面並有利於負載分佈. 狗尾端帶錐形截面尾

Serrations under head / Hexalobular socket ISO 10664

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) 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.

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.
