Delta Protekt Wedge Locking Washer Zinc Plated

• The Delta Protekt washer system consists of a pair of washers with a wedge-locking action, which is a unique method that uses tension instead of friction.
• The key is the difference in angles. Since the angle A is larger than the angle B , the pair of washers expand more than the corresponding pitch of the thread.
• The washers positively lock the fastener in a joint which is subjected to extreme vibration or dynamic loads.
• This unique bolt securing system uses tension to make the bolt self-locking.

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 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.
