Why are the Threadlockers not full of material?
Threadlockers cure differently than most other adhesives. They are called anaerobic adhesives and thus cure with an ABSENCE of air. Therefore they must have air in the container to keep them from curing! They compound their curing abilities when they come in contact with metal as well! Therefore, we highly recommend that you do not use the metal tips, since the combination of metal and the absence of air while traveling down the these narrow tips will make the material cure very quickly.
