Professional Applications & Engineering Value
These M3 flat head screws are engineered to solve critical sealing challenges in industrial applications where fluid or gas containment is paramount. The combination of 18-8 stainless steel and a passivated finish provides excellent resistance to corrosion, extending service life in moist or chemically aggressive settings. The integrated silicone rubber O-ring ensures a tight seal against high pressure (up to 6000 psi) and extreme temperatures, making these metric screws ideal for hydraulic systems, pneumatic equipment, and machinery enclosures. The undercut flat head and Phillips drive facilitate quick, flush installation, reducing assembly time while maintaining a secure, leak-proof joint that withstands operational stresses.
Specification Summary & Compliance
This screw meets DIN 965 specifications, with M3 x 0.5 mm coarse pitch threads manufactured to Class 6g tolerance for precise fit. It is fully threaded for consistent holding power and features an 8 mm length and 90° countersink angle. Compliance is assured with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible sourcing and use in global markets.
