So I have a 79' wellcraft sunhatch 196 with a swim ladder that has 4 screws holding to the back of the boat. One screw has come loose and walked itself out just a little. I took the screw out and it's a good size screw about 3" long heavy duty. But screw won't thread tight. So.... Today I put a good amount of 3m 5200 in the hole and tightened the screw as much as possible.... Will it hold??????
