Modified Truss Tek Screw, Plated

Phillips Modified Truss head self drilling screws are fasteners that have a drill point which enables users to drill them directly into material without having to pre-drill a hole. These screws feature a phillips drive and have an extra wide head that is an integrally formed round washer with a low rounded top that is approximately 75% the diameter of the washer. Modified Truss Head screws have a 100° undercut which creates a larger area beneath the the screw's head for a larger bearing surface. These fasteners are available in a zinc plated finish.
