Bob Schmidt teaches the secrets to tighten & keep tight those loose bolts in simple steps. First buy a removable blue thread locker and keep it ready to use. Check for any loose door locks or bolts in your house and remove its screw. Squeeze some thread locker out and apply it to the screw and stay away from carpets while squeezing it out. Let it set on the screw for about 5 minutes and fit the screw back. It can also be used in nuts and bolts and bath accessories.
