Stainless steel hexagonal tapping screws are mechanical parts, mainly used for connecting thin metal plates (such as steel plates, sawn plates, etc.). The head of this screw is a regular hexagon, and its thread surface has a high hardness (≥HRC45), which can tap the internal thread in the threaded bottom hole of the connected part to form a connection.
The material of stainless steel hexagonal tapping screws is usually stainless steel SUS201 or SUS304 or above.
GNEE supplies a variety of types including thread forming tapping screws, thread cutting tapping screws, thread rolling tapping screws and self-drilling tapping screws. It can be customized according to customer needs, including different head shapes, thread specifications, surface treatments, etc., to meet various specific application requirements.
