Diameter specifications: Common tantalum screw diameters include M2, M3, M4, M5, M6, M8, etc. Screws of different diameters are suitable for connection parts with different thickness and strength requirements

Length specification: The length depends on the specific usage scenario and connection requirements, generally ranging from a few millimeters to tens of millimeters. For example, the length of tantalum screws used in electronic devices may be shorter, while the length of tantalum screws used in some large machinery or equipment may be longer.

Pitch specification: Pitch refers to the distance between adjacent threads, and common pitch specifications include coarse and fine threads. The coarse tooth pitch is relatively large, suitable for general connection occasions, with high connection strength and fast tightening speed; Fine tooth pitch is small, suitable for situations that require high connection accuracy or need to withstand large vibrations, and can provide a tighter connection.
