Key Features & Benefits at a Glance
- Exceptional corrosion resistance in harsh environments thanks to premium 316 stainless steel construction
- Superior mechanical strength with 75,000 psi tensile strength and Rockwell B83 hardness for reliable, long-lasting fastening
- Integrated flange design eliminates the need for a separate washer, providing a larger bearing surface and faster assembly
- Secure and efficient installation with a 2.5mm hex drive that offers excellent torque transfer and resists cam-out
- Precise and reliable thread engagement ensured by the Class 6g tolerance for metric coarse (0.7mm pitch) threads
- Low-profile, rounded button head provides a finished appearance and reduces the risk of snagging
- Compliant with major environmental regulations including RoHS 3 and REACH for use in regulated industries
Professional Applications & Engineering Value
This M4 flanged button head screw is engineered to solve critical challenges in industrial assembly. The 316 stainless steel material offers superior resistance to chemicals and saltwater, making it ideal for marine, chemical processing, and food-grade equipment where corrosion is a primary concern. The fully threaded design with a coarse 0.7mm pitch ensures rapid installation and high vibration resistance in machinery and structural frameworks. The integrated flange distributes clamping force effectively, preventing surface damage and maintaining joint integrity. Combined with the reliable hex drive, this screw delivers consistent performance in high-stress applications, reducing maintenance needs and downtime.
Specification Summary & Compliance
This screw conforms to metric (M4 x 0.7mm) specifications with a Class 6g thread fit for standard industrial use. The dimensional profile includes a 20mm length and a 12.2mm flange diameter. It is manufactured to provide a tensile strength of 75,000 psi and a hardness of Rockwell B83. 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 global supply chains.
