Professional Applications & Engineering Value
These M4.2 x 25mm metric tapping screws are engineered to solve common fastening challenges in metal and sheet metal applications. The thread cutting design allows the screw to form its own mating thread, reducing labor and tooling costs by eliminating tapping operations. Made from durable 18-8 stainless steel, they resist rust and corrosion in demanding environments, while the Phillips oval head provides a secure drive and a clean, finished look when seated. This combination of material strength and efficient threading technology ensures reliable performance in assembly lines, electrical enclosures, and automotive components, where vibration resistance and long-term integrity are critical.
Specification Summary & Compliance
This screw features a M4.2 thread diameter (0.17"), 25mm length, and is fully threaded with a right-hand direction for standard installation. It conforms to DIN 7983 (equivalent to ISO 7051) for dimensional precision, including an 80° countersink angle and standard oval head profile. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets international environmental and safety standards for industrial use.
