Forgefix 100HDWASH4 Flat Washer Heavy-Duty Zp M4 Bag 100

These Forgefix heavy-duty Form A Flat Washers are thicker than the more popular Form B type washers. They are bright Zinc Plated for increased corrosion resistance and conform to DIN 125 standards. Washers provide a smooth surface for the nut or bolt to bear on making it less likely to loosen as a result of an uneven fastening surface. The main purpose of a washer is to distribute the load under a bolt head or the nut face. APPLICATION:On all manner of bolting applications. 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 substrate’s 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.Flat Washer Heavy-Duty ZP M4 Bag 100PTDFORHDWASH4M
