Bent eye screws

a) DIN 966 refers to a standard for countersunk raised head screws with a cross recess drive (commonly Phillips or Pozi)

b) The screw head is partially countersunk but has a domed or raised top, providing a semi-flush and decorative appearance.

a) ISO 7380-2 specifies the standard for hexagon socket button head screws with collar. Generic hexalobular socket (6 lobe) is another common alternative used in various applications. 

b) This screw features an extended cylindrical tip, known as a dog point, at the end of the threaded portion, enabling precise alignment and positioning in mating components.

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.

Screw refer to ISO 14581

a) A self-drilling screw is a type of screw designed to drill its own hole and tap its own threads into materials as it is driven in, eliminating the need for a pre-drilled hole. The screw features a drill-like tip, often referred to a self-drilling tip, which helps the screw cut through the material. This makes installation faster and more efficient. 

b) Serrations under head create additional friction between screw head and the material. The serrated surface provides better grip for tools like screwdrivers, allowing more torque to be applied during installation.
