Flangeless Plugs are made of silicone and suitable for use on screw holes from M4 to M33. They can also be used for unthreaded holes from 2mm up to 31.7mm. Flangeless Plugs are hollow, which allow for flexibility. They have soft ribs that seal the hole entrance superbly. The soft ribs also prevent excessive adhesion of paint to the screw inlet. Flangeless Plugs have a curved feature at the back for easy grip and handling.
