Difference between lock screw and self-tapping screw

If you want to know the difference between a lock screw and a self-tapping screw, you must first understand the concept of both. That is, you must first figure out what is the anti-loose screw, what is the self tapping screws , what are their functions?

Knowing these two points, the difference between the two is naturally presented.First understand what is called anti-loose screw: The anti-loose screw was first created in the United States.

It is sprayed on the thread with a special engineering plastic with a main component of nylon as a thermal spray technique. When the thread is tightened, this layer of engineering plastic is Kneading and strong reaction and friction, then hinder the screw to retreat and reach the anti-loose effect.

Another kind of anti-loose screw is a dispensing screw, which is anti-loose screw glue, anti-loose screw pre-applied glue, anti-loose glue, is a high viscosity, non-toxic, touch deformation, water-based pre-coated thread sealant, suitable for Actively apply glue. After boring, the product becomes a kind of elastic, strong adhesion, no need to cure the sealant, can be used for the sealing of tapered or straight threads.
