when i apply loctite i hold the grub screw with my 1.5 Hex Driver then i have it just pointed up tilted forward a little then just sqeeze the bottle to u see the loctite starting to get near the top of the cap. then i sort of hold the bottle in 1 hand and my 1.5 with the grub in the other then u sorta point the tip of the bottle towards the screw and rotate your 1.5 and spin a fine ammount other the threads of the grub screw. Lol. i guess that sounds confusing ( it also helps to cut the tip of the bottle on a slight angle \
