Professional Applications & Engineering Value
These M5 flat head screws deliver critical engineering solutions where surface flushness and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for machinery, electrical enclosures, and automotive components exposed to moisture or chemicals. With fully threaded coarse pitch design and Class 6h thread fit, these metric fasteners prevent loosening under vibration while enabling rapid installation in sheet metal, plastic assemblies, and structural frameworks. The standardized JIS B 1111 specification ensures perfect compatibility with existing metric tooling and components, reducing inventory complexity across manufacturing and maintenance operations.
Specification Summary & Compliance
This M5 x 0.8mm x 30mm flat head screw maintains precision Class 6h thread fit per metric standards with fully threaded configuration. Manufacturing strictly follows JIS B 1111 specifications for dimensional accuracy, including 10mm head diameter, 2.8mm head height, and standard 90° countersink profile. The product is fully compliant with RoHS 3 (2015/863/EU) environmental regulations, containing no restricted hazardous substances for global market acceptance.
