Professional Applications & Engineering Value
This M4 metric screw is engineered to address common industrial fastening challenges, such as vibration loosening and corrosion-induced failure. The 316 Stainless Steel material offers exceptional resistance to saltwater, chemicals, and extreme temperatures, making it suitable for marine, chemical processing, and outdoor equipment. The flanged button head design eliminates the need for separate washers, streamlining assembly while providing a wider bearing surface to protect softer materials. Combined with the Class 6g coarse thread and fully threaded shank, it ensures rapid installation and reliable holding power in industrial fasteners applications, from machinery enclosures to structural frameworks.
Specification Summary & Compliance
This screw adheres to metric thread standards with M4 x 0.7mm coarse pitch and Class 6g thread fit for consistent dimensional accuracy. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. The fully threaded design and specified mechanical properties, including tensile strength and hardness, ensure reliable performance in demanding industrial applications.
