Tiny screw M2.5

Steel weld stud fully threaded

a) DIN 965 specifies the standard for countersunk head screws with a cross recess drive (commonly known as a Phillips drive). These screws are designed to sit flush with the material’s surface when installed, ensuring a smooth and clean appearance.

b) The cross-recessed drives, such as Phillips and Pozi, are widely used for their ease of installation and removal with compatible screwdrivers. Additionally, the hexalobular socket (6-lobe) design is commonly employed to provide improved torque transfer and minimize the risk of cam-out during fastening.

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 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.

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.

a) The screw head features a hexalobular socket, often referred to by the generic name “6 lobe”

b) The flat underside of the pan head distributes clamping force over a larger area compared to countersunk or round head screws.

c) Although there may be minor differences in dimensional tolerances or thread requirements, both DIN 7985 (German standard) and ISO 14583 (international standard) specify pan head screws.
