a) DIN 912 (ISO 4762) refers to a standard for metric socket head cap screws, also known as cup head screws. These fasteners feature a cylindrical head with a hexagonal recess (socket) in the center, allowing them to be tightened or loosened using a hex key or Allen wrench. These screws are commonly used in various applications where a high tensile strength is required.

b) A socket head cap screw with a knurled head is a modified version of the standard DIN 912 screw, featuring a textured knurled surface around the head. This design provides additional grip for manual handling or adjustment, making it ideal for certain applications.

a) DIN 968 specifies the standard for cross-recessed pan head tapping screws with a collar. The screws are commonly available with two types of cross recess drives: Type H (Phillips) and Type Z (Pozidriv), both designed for easy installation and removal.

b) There are two types of thread ends specified in DIN 7970 (Tapping Screws): Type C, which features a cone point, and Type F, which has a flat end.

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.
