Material & Surface Treatment Comparison

Selecting the correct finish directly affects service life in different working environments. Slotted Pan Head Self Tapping Screws DIN 7971 A2 Stainless Steel Natural Finish offers superior rust resistance compared with conventional carbon steel tapping screws. We list common options for your reference:

1. A2 Stainless Steel Natural Finish: Suitable for indoor and mild outdoor environments, zero risk of coating peeling

2. Stainless Steel Black Oxide: Matte black appearance for decorative assembly, limited anti-corrosion performance

3. Zinc Plated Carbon Steel: Cost-effective alternative, only recommended for dry indoor conditions; not compatible for pairing with stainless steel components
