Professional Applications & Engineering Value

This zinc-plated steel rounded head screw delivers critical performance where corrosion resistance and mechanical reliability intersect. The M3.5 fully threaded design with coarse 0.6mm pitch provides rapid installation in sheet metal assemblies, electrical enclosures, and machinery panels. Engineered to DIN 85/ISO 1580 standards, the Class 6h thread fit maintains precise tolerances while the slotted drive pan head offers compatibility with standard tools. With 60,000 psi tensile strength and Rockwell B71 hardness, it withstands vibrational stresses in automotive subsystems, industrial controls, and outdoor equipment where fastener integrity is non-negotiable.

Specification Summary & Compliance

Manufactured to DIN 85/ISO 1580 dimensional standards with Class 6h thread tolerance for metric coarse threading. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The zinc-plated steel construction meets industrial corrosion protection requirements while maintaining 60,000 psi tensile strength and Rockwell B71 hardness specifications.
