Professional Applications & Engineering Value

This M2.5 metric sealing screw is engineered to address common challenges in industrial and precision engineering applications where fluid or gas containment is critical. The combination of 316 stainless steel and a silicone rubber O-ring provides a robust barrier against moisture, chemicals, and pressure fluctuations, preventing system failures. The undercut flat head design ensures a countersunk fit that minimizes protrusion and maximizes the sealing area, ideal for compact assemblies in electronics enclosures, fluid handling systems, and automotive components. With a fully threaded body and Phillips drive, installation is straightforward, reducing assembly time while maintaining a secure, leak-proof seal under high-pressure conditions up to 6000 psi.

Specification Summary & Compliance

This screw adheres to precise dimensional standards, including M2.5 x 0.45mm coarse metric thread with a Class 6g tolerance for consistent fit. It conforms to DIN 965 specifications for flat head screws, ensuring interchangeability and reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting use in environmentally conscious and regulated industries.
