Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction and passivated finish.
- Reliable fastening performance with a high 70,000 psi tensile strength and Rockwell B80 hardness for demanding applications.
- Efficient installation and removal with the standard Phillips drive (No. 1) and coarse pitch threading.
- Precise thread fit and interchangeability ensured by Class 6g thread tolerance and compliance with the DIN 965 standard.
- Flush, low-profile installation ideal for confined spaces, provided by the flat head design and 90° countersink angle.
- Full-length threading (M3 x 0.5mm x 12mm) for maximum grip and holding power across the entire shank.
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental regulations.
Professional Applications & Engineering Value
Engineered for reliability, this M3 flat head screw in 316 stainless steel addresses critical challenges in industrial assembly. Its exceptional material grade offers outstanding resistance to chemicals and saltwater, preventing failure in marine, chemical processing, and outdoor applications. The passivated finish further enhances surface durability, reducing the risk of galling and corrosion-induced seizing. The Phillips drive and coarse pitch metric thread enable quick, secure fastening, even in high-vibration environments, while the flat head profile ensures a smooth, flush finish that eliminates protrusions in machinery and electronic enclosures. This combination of high-strength and corrosion-resistant properties makes it a trusted industrial fastener for long-term performance.
Specification Summary & Compliance
This screw features precise M3 x 0.5mm coarse threads with a Class 6g thread fit per ISO metric standards, ensuring dimensional accuracy and interchangeability. Manufacturing and quality are governed by the DIN 965 specification. 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 and safe for use in regulated markets.
