These Forgefix Shake Proof washers are designed to allow a secure fastening, preventing loosening of the fastener by either movement or vibration. Also known as serrated washers or star washers, they have serrations that extend radially inward and/or outward to bite into the bearing surface. This type of washer is effective as a lock washer when used with a soft substrate, such as aluminium or plastic.
The washers are bright zinc plated for increased corrosion resistance and conform to DIN6797 standards.
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 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.
