Pre-applied is a coating applied to threaded screws, bolts and pipe fittingswhich is a Dry-to-Touch threadlocker or thread sealer.

It is normally used on high volume parts. Therefore, the customer can use the coated parts with automatic assembly equipment, with the guarantee that the product is applied correctly. With pre-applied solutions, there is no need to apply adhesives, sealants or any other locking or sealing material during assembly.
