Professional Applications & Engineering Value

These M2.9 coarse thread tapping screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and installation inefficiency. Made from 18-8 stainless steel, they offer exceptional resistance to rust and corrosion, which is critical in outdoor or humid conditions. The thread forming design (Type C) eliminates the need for separate tapping operations, as the pointed tip and fully threaded body cut precise threads directly into the metal, reducing labor costs and preventing stripping. With a pan head and Phillips drive, they provide a flush finish and easy torque application, ideal for automated or manual assembly lines in automotive, electronics, and HVAC systems. This combination ensures reliable, long-lasting fastening that withstands vibration and thermal cycling.

Specification Summary & Compliance

These screws adhere to DIN 7981 standards, ensuring precise dimensional accuracy and performance in metric coarse thread applications. They feature a right-hand thread direction and are fully threaded for consistent engagement. Compliance with RoHS 3 (2015/863/EU) confirms they are free from hazardous substances, making them suitable for environmentally conscious industries. The specifications include a screw size of M2.9, length of 9.5 mm, and maximum drilling thickness of 0.025", designed for efficient use in sheet metal and other thin materials.
