Serrated Washers Zinc Plated (External)

• A washer with serrations that extend radially inward or outward to bite into the bearing surface.
• They can resist rotation more than a plain washer on hard surfaces, as the tension between washer and the surface is applied over a much smaller area.
• The washers are bright zinc plated for increased corrosion resistance and conform to DIN6797 standards.

APPLICATION

On all manner of bolting applications where movement or vibration may cause loosening typical examples would be furniture applications such as stadium seating as well as engineering machinery application.

Can be used with all types of bolts and nuts.

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.
