Screw Grip is a paste-like fluid which hugely increases the friction between the tool and the screw or nut being turned. Screwed connections which are relatively inaccessible can therefore be protected from damage and screws which have already been damaged can be unscrewed easily.

Shake well before use. Place a single drop of Screw Grip in or around the damaged screw head. Place the tool accurately on the screw head and turn it from left to right so that the crystals anchor into each other. The tool will soon find its grip and the screw can be without any difficulty.
