Lesson 4: FAQs
FAQs
Can thread locking compounds be used on plastic threaded assemblies?
Anaerobic thread locking compounds can not be used on plastic threads.
Will threadlockers work on stainless steel fasteners?
Yes, threadlockers can be used on inactive metal like stainless steel. We require the addition of Permatex Surface Prep Activator for Anaerobics to the fastener threads prior to adding the threadlocker.
I applied the threadlocker and the excess that I see around the bolt head is still uncured after 24 hours. Will this cure?
The excess threadlocker that is seen will not cure and can easily be wiped away. Anaerobic threadlockers cure with the absence of air in the presence of active metals. So the unseen threadlocker will cure.
How much threadlocker do I apply to the threaded fastener?
Only apply a small amount of threadlocker by covering one side of the first three threads of the fastener.
Can bolts be easily removed when threadlocker is used?
This depends on the type of threadlocker being used. The Blue medium strength threa lockers, and High Strength Removable Orange threadlockers can be removed with normal hand tools. The Red Threadlockers will require localized heat and hand tools to loosen and remove.
What is the correct way to prepare the threaded surface before applying threadlocker?
Use a wire brush to remove any corrosion from the threaded surfaces. You may want to use Service Prep Activator for Anaerobics, as this will cut the cure time in half, and is especially good for use in cold temperatures. It is also recommended for use on inactive metals (stainless steel, aluminum, and zinc coated fasteners).
