Bent eye screws

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) Unlike DIN 912, DIN 7984 screws features a low-profile head and a hexagonal socket drive (Socket thin head cap screws) with metric thread ranging from size M3 to M24

b) DIN 7984 screws have a thinner head because they are designed to be countersunk, allowing them to sit flush with the material surface. However, this design may not provide the same torque transfer capacity as the thicker head of DIN 912 screws, which are designed to handle higher torque due to their thicker cylindrical head shape.

Extremely low head

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) 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) Three indentations on the thread allow better debris clearance and assist in the thread-forming process.

c) A standard trilobe thread forming screw without indentations is avaialble upon request.
