Key Features & Benefits at a Glance
- Superior corrosion resistance for demanding environments thanks to 316 stainless steel construction and a passivated finish.
- Reliable fastening in coarse-thread applications with a 0.7mm pitch for quicker installation and reduced cross-threading risk.
- Precise thread fit and interchangeability ensured by the Class 6g tolerance, meeting stringent DIN 963 standards.
- High mechanical strength with a 100,000 psi tensile strength for secure, long-lasting connections under load.
- Flush surface installation enabled by the standard flat head and 90° countersink angle.
- Broad industrial compliance with RoHS 3 and REACH regulations, ensuring material safety and environmental responsibility.
- Full-length threading (10mm) provides maximum grip and holding power along the entire fastener length.
Professional Applications & Engineering Value
This M4 flat head screw is engineered to solve critical challenges in industrial and marine settings where corrosion resistance is paramount. The core value lies in its 316 stainless steel material and passivated finish, which work synergistically to drastically slow oxidation and pitting, even when exposed to chlorides or harsh chemicals. The coarse thread spacing (0.7mm pitch) and Class 6g thread fit ensure rapid, reliable assembly with a lower risk of thread galling or stripping in softer materials or pre-tapped holes. This combination makes it an indispensable metric screw for applications requiring a flush finish—such as machinery panels, electrical enclosures, and automotive components—where a secure, vibration-resistant, and aesthetically clean fastening solution is demanded, all while adhering to the precise dimensional requirements of DIN 963.
Specification Summary & Compliance
This fastener features a Class 6g thread fit per ISO metric standards, ensuring dimensional precision and interchangeability. It is manufactured to conform to the DIN 963 specification for flat head screws. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances.
