M12 Threaded Rod Zinc Plated

• These threaded rods are bright zinc plated for increased corrosion resistance, and provide a cost effective fastening solution for many varied applications.
• They can be used with many other products including drop in anchors and masonry anchor shields.
• Conform to DIN975 standards.
• Available in grades 4.8 and 8.8.

Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.
