Tiny screw M2.5

a) It is a standard that defines the specifications for cross recessed raised cheese head screws (Pan Head). These screws have a raised cylindrical head with a flat bearing surface and a cross recess, often referred to as a Phillips drive (Type H). Some other common types are cross recess type Z (Pozi) and Generic hexalobular socket / 6 lobe. 

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.

Cross recee type H (phillips) is available upon request

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.

Extremely low head

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.
