Professional Applications & Engineering Value

This M3 pan head slotted screw delivers exceptional engineering value across multiple industrial sectors. The 18-8 stainless steel composition combined with passivated surface treatment creates a robust barrier against corrosion, making it ideal for applications exposed to moisture, chemicals, or outdoor elements. The metric coarse threading with precise Class 6g tolerance ensures reliable engagement in machinery, electronic enclosures, and assembly fixtures where vibration resistance is critical. The rounded pan head profile provides a low-profile finish while the slotted drive accommodates standard screwdrivers, offering practical installation solutions for maintenance teams and production lines alike. These fully threaded fasteners maintain consistent clamping force in automotive components, industrial equipment, and precision instruments where dimensional stability and corrosion resistance are paramount.

Specification Summary & Compliance

This precision fastener features M3 x 0.5mm coarse pitch threading with Class 6g thread fit according to metric standards. The 20mm fully threaded length and 6mm pan head diameter provide standardized dimensions compatible with ISO 1580 DIN 85 specifications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications while maintaining the 70,000 PSI tensile strength characteristic of 18-8 stainless steel construction.
