Professional Applications & Engineering Value
Engineered for high-stress environments, these M4 metric flat head screws made from A286 stainless steel provide outstanding resistance to corrosion and heat, making them ideal for aerospace, automotive, and heavy machinery applications. The Torx T20 drive minimizes tool slippage, enhancing worker safety and assembly speed, while the fully threaded coarse pitch design ensures rapid installation and strong holding power in materials prone to vibration. With a 90° countersink angle, these screws sit flush, reducing protrusion risks and improving aerodynamic or aesthetic surfaces. This combination of high tensile strength and precise Class 6g thread fit addresses common failure points, offering durable performance in critical assemblies where reliability is non-negotiable.
Specification Summary & Compliance
This product adheres to metric thread standards with an M4 x 0.7mm coarse thread and Class 6g tolerance for consistent fit. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Dimensions include a 16mm length, 9.1mm head diameter, and 2.8mm head height, supporting precise engineering requirements.
