Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel and passivated finish, ideal for harsh environments and extended service life.
- Enhanced load distribution and secure seating thanks to the integrated flange, which acts like a built-in washer to prevent loosening.
- High-strength fastening with a tensile strength of 70,000 psi, ensuring reliable performance in demanding applications.
- Quick and easy installation with a 4 mm hex drive, allowing for efficient assembly with standard tools.
- Precise and reliable thread engagement with a Class 6g thread fit, providing consistent performance and reducing the risk of cross-threading.
- Broad industrial compatibility as a fully threaded M6 coarse pitch screw, conforming to the widely recognized ISO 7380 standard.
- Safe for regulated industries with compliance to RoHS 3 and REACH, ensuring environmental and safety standards are met.
Professional Applications & Engineering Value
This 316 Stainless Steel flanged button head screw is engineered to solve critical challenges in industrial assembly. The passivated finish significantly enhances the innate corrosion resistance of the 316 alloy, making it a top choice for applications exposed to moisture, chemicals, and salt spray, such as in marine, chemical processing, and food & beverage equipment. The flanged design eliminates the need for a separate washer, streamlining inventory and speeding up installation while providing a larger bearing surface to protect softer materials and resist vibration-induced loosening. Combined with the reliable M6 coarse thread and 4 mm hex drive, it delivers a robust and efficient fastening solution for machinery, enclosures, and structural frameworks where durability and compliance are non-negotiable.
Specification Summary & Compliance
This screw features an M6 x 1 mm coarse thread with a Class 6g tolerance for precise fit. It is fully threaded and has a length of 40 mm with a flange diameter of 13.6 mm. Manufactured in accordance with ISO 7380 and is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant.
