Professional Applications & Engineering Value

These M2.5 metric screws with zinc-plated steel construction address critical industrial challenges where corrosion resistance and reliable fastening are paramount. The coarse thread pitch (0.45mm) combined with Class 6g fit provides exceptional vibration resistance in automotive assemblies, electronic enclosures, and machinery components where loosening under dynamic loads is a concern. The rounded pan head design distributes clamping force evenly, preventing damage to sensitive materials while the JIS drive system ensures compatibility with standard industrial tools. Fully threaded along the entire 12mm length, these fasteners deliver maximum thread engagement for superior pull-out strength in sheet metal, plastic, and thin-material applications where strip-out failure must be prevented.

Specification Summary & Compliance

Manufactured to precise metric dimensions with M2.5 thread size and 0.45mm coarse pitch, these screws feature Class 6g thread tolerance for industrial-grade fit. The 12mm length maintains tight -0.6 to 0 mm tolerance for consistent installation depth. Compliance includes JIS B 1111 standard for dimensional accuracy and mechanical properties, along with RoHS 3 (2015/863/EU) compliance for environmental safety in global markets.
