Use Screw pliers to loosen and unscrew screws that have a damaged head profile and cannot be unscrewed with standard tools. Damage on the screw’s profile usually occurs when screws are stuck due to gluing or corrosion and standard tool strips the profile. Pliers have horizontal and also vertical serrated teeth, which grab the screw by the outer diameter of the head. Teeth are strong and very sharp and provide excellent grip on screw`s head, regardless of its profile.
Pliers can be used on screw heads with diameter from 3 to 11 mm.
