Professional Applications & Engineering Value

Engineered for industrial fastening applications requiring both structural integrity and corrosion protection, this M4 metric flat head screw addresses critical challenges in machinery assembly, electronic enclosures, and automotive components. The zinc-plated steel construction provides essential galvanic protection against moisture and chemical exposure, while the coarse 0.7mm pitch threading ensures rapid installation and maintains grip under vibration-prone conditions. The fully threaded design distributes clamping force evenly across the entire 16mm length, preventing joint loosening in dynamic loads. With its JIS B 1111 standard compliance and 90° countersink angle, it delivers reliable performance in applications where flush mounting and standardized drive systems are paramount for maintenance efficiency.

Specification Summary & Compliance

This flat head screw maintains Class 6h thread fit precision per metric standards, with dimensional accuracy governed by JIS B 1111 specifications. The manufacturing process adheres to strict tolerance controls for 8mm head diameter and 16mm length consistency. Regulatory compliance includes full adherence to RoHS 3 (2015/863/EU) environmental directives, ensuring restriction of hazardous substances in professional and industrial applications.
