Professional Applications & Engineering Value
This M4 flat head screw is engineered to address common industrial challenges such as corrosion-induced failure and inconsistent thread fit. Manufactured from 316 Stainless Steel with a passivated finish, it excels in aggressive settings—including marine, chemical processing, and outdoor equipment—where moisture and chemicals degrade ordinary fasteners. The fully threaded design and Class 6g thread fit provide uniform load distribution and vibration resistance, critical for machinery, enclosures, and structural assemblies. By integrating a 90° countersink angle and slotted drive, it ensures smooth, flush installations in pre-drilled holes, minimizing protrusions and improving aesthetics. Ideal for OEMs and maintenance teams, this metric screw delivers long-term reliability while reducing downtime and replacement costs.
Specification Summary & Compliance
This product adheres to precise dimensional and performance criteria, including M4 x 0.7 mm coarse thread pitch with Class 6g thread fit per ISO metric standards. It meets DIN 963 specifications for flat head screws, ensuring interchangeability and quality. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of restricted substances for safe industrial use.
