S-90505A437 M2.5 x 8 mm DIN 965 Sealing Stainless Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction for reliable performance in harsh environments, extending service life.
• Effective sealing up to 6000 psi thanks to the integrated Buna-N rubber O-ring, preventing leaks in pressurized applications.
• Broad temperature compatibility from -40° to 225° F, ensuring seal integrity and screw performance across diverse operating conditions.
• Precise and secure fastening with a Class 6g thread fit and coarse pitch (0.45mm), enabling quick assembly and high vibration resistance.
• Streamlined, low-profile installation with an undercut flat head design that sits flush, ideal for space-constrained applications.
• Effortless drive engagement using a standard Phillips No. 1 drive, simplifying installation and reducing tool slippage.
• Guaranteed dimensional consistency and interchangeability by conforming to the DIN 965 standard for metric flat head screws.

Professional Applications & Engineering Value

This M2.5 metric sealing screw is engineered to solve critical challenges in industrial assembly where both a secure mechanical fastening and a reliable environmental seal are required. The combination of 316 Stainless Steel, known for its excellent resistance to chemicals and corrosion, and the Buna-N rubber O-ring creates a robust sealing solution for enclosures, fluid handling systems, and machinery subjected to moisture, dust, or pressure variations up to 6000 psi. The undercut flat head profile ensures a flush finish, preventing snagging and providing a clean aesthetic, while the coarse thread and Class 6g tolerance facilitate rapid, stable installation into a maximum hole diameter of 2.946 mm, reducing assembly time and improving production efficiency in automated or manual settings.

Specification Summary & Compliance

This screw features a fully threaded M2.5 x 0.45 mm coarse pitch with a Class 6g thread fit and a 90° countersink angle, manufactured to the precise dimensional requirements of the DIN 965 standard. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for use in global industrial markets.
