Professional Applications & Engineering Value
This M2.5 flat head screw is engineered to solve critical sealing and corrosion challenges in demanding industrial applications. The combination of 316 Stainless Steel and a Buna-N rubber O-ring provides a durable barrier against moisture, chemicals, and extreme temperatures from -40° to 225° F, making it perfect for pneumatic systems, fluid handling equipment, and outdoor machinery. The undercut flat head profile and Phillips drive allow for easy, countersunk installation that resists cam-out and maintains a smooth surface. With a fully threaded metric coarse thread and Class 6g tolerance, it ensures consistent clamping force and vibration resistance, enhancing assembly integrity in automotive, marine, and chemical processing environments where reliability is non-negotiable.
Specification Summary & Compliance
This screw features precise M2.5 x 0.45 mm metric coarse threads with a Class 6g fit for dimensional accuracy. It is manufactured in compliance with DIN 965 specifications and is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to international environmental and safety standards for industrial fasteners.
