The knobs on my dresser drawers keep coming loose. The knob are metal and the screws go through from the inside of the drawers and stir into the knobs about 3/8". Any suggestions as to how to hang on to them from coming loose all the time? Thanks!
Get some "lock tite" from your auto parts store. or try putting nail polish on the threads and screw them tight and consent to it dry overnight. Try putting some glue on the threads, then put the knob back on.
depending on what the knob insert is made of you can do a couple things.

if your knob is wooden and the threads are wooden you can put some wood paste in there and after tighten the screw back up real tight.

if the insert is metal you can put a mop of loctite (blue) on the screw and retighten the knob.
Answers:    Fireman4 is correct, Cassie. Put locktite on threads and you should have no trouble.
Use a product called lock tight.you can seize it auto zone or car parts store or most hard ware stores or if you don't want them to ever come of use super bonding agent. I used a product close to lock tight but cheaper its called shoe goo and smells terrible but is heck when it sets up. Here within Okla its less than $3.00 for a tube.
It sounds like they might be stripped. You can get unusual nobs fairly cheep at Lowes. You could also taken one off and bring both the knob and the screw beside you they might not be the right size for each other. New screws would be just about a buck. Take the screw and wind some sewing thread around the spirals of the screw. Put some white glue on the screw near the thread and screw the knob into the threaded, glued screw. Should hold it.
They are the darn-est things. It really hard to do.I lately keep tighten them up.
