SCREW TIGHTLY

SCREW IN TIGHTLYIn cases when you want to prevent turning of the screw, screwed into a Board or plywood, I use a very simple way. Of stiff wire or a nail, whose diameter corresponds to the width of the slot of the screw, hollow out a U-shaped bracket and pin it as shown in the figure. Upon entering the slot, it securely holds the screw.
