Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or chemically aggressive environments.
- Reliable high-pressure sealing up to 6000 psi, preventing leaks in critical fluid and gas systems.
- Wide temperature tolerance from -80° to 400° F, ensured by the integrated silicone rubber O-ring for stable performance.
- Secure and flush installation with the flat undercut head and Phillips drive, providing a clean finish and reduced risk of snagging.
- Consistent and precise fit due to the Class 6g thread tolerance and coarse pitch, enabling faster assembly and reduced cross-threading.
- Enhanced durability in demanding applications with a high tensile strength of 70,000 psi and full threading for maximum grip.
- Compliance with international standards including DIN 965, ensuring quality and interchangeability in global industrial projects.
Professional Applications & Engineering Value
This M2.5 metric screw is engineered to solve critical sealing and corrosion challenges in industrial applications. The combination of 316 stainless steel and a silicone rubber O-ring provides a robust seal against moisture, chemicals, and extreme temperatures, making it perfect for high-pressure environments like hydraulic systems, marine equipment, and processing machinery. The flat head with undercut and Phillips drive allows for a countersunk, low-profile installation, reducing fluid turbulence and part interference. With a coarse thread and Class 6g fit, it ensures quick, reliable fastening even in vibrating conditions, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including a Class 6g thread fit and DIN 965 specifications for flat head screws. It is fully threaded with a coarse M2.5 x 0.45 mm pitch and right-hand direction. Compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for regulated industries.
