Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M4 metric nylon flat head screws solve critical challenges in electrical enclosures, automotive components, and food processing equipment where metal fasteners cause short circuits, corrosion, or contamination. The nylon plastic material provides excellent electrical insulation and chemical resistance while the Class 6g thread precision ensures vibration-resistant connections in assembly lines. With full threading and coarse 0.7mm pitch, these fasteners deliver rapid installation and superior pull-out strength in plastic and soft material applications. The 90° countersink angle and flat head profile create seamless finishes in countersunk holes, making them ideal for consumer products, machinery guards, and panel assemblies where aesthetics and safety matter.

Specification Summary & Compliance

These metric flat head screws feature M4 x 0.7mm coarse threads with Class 6g tolerance per ISO metric standards, ensuring precise fit in threaded holes. The 30mm length and 9.4mm head diameter provide optimal proportions for various mounting depths. Manufacturing complies with ASME B18.6.7M specifications for dimensional consistency and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming absence of restricted substances for global market acceptance.
