Professional Applications & Engineering Value
This M4 metric screw with rounded button head and hex drive addresses critical challenges in precision assembly. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for automotive components, electronic enclosures, and marine equipment where moisture resistance is paramount. The coarse pitch threading (0.7mm) ensures rapid installation and superior vibration resistance compared to fine-thread alternatives. The integrated vented design enables pressure equalization in sealed systems, preventing diaphragm distortion in sensor housings and fluid management systems. With its fully threaded configuration and Class 6g thread fit, this fastener delivers consistent clamping force across the entire engagement length, eliminating the need for additional sealing components in many pressurized applications.
Specification Summary & Compliance
This metric fastener features M4x0.7mm coarse threads with Class 6g tolerance per ISO metric standards, ensuring precise thread engagement. The 16mm length provides optimal engagement depth for medium-duty applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material transparency. The hex drive system maintains ISO 10664 compatibility for standard tooling.
