Plastic top pins and nails (commonly referred to as polytops) are a unique range of self masking fasteners specially developed for use on all exposed fixing areas particularly UPVC and other maintenance free profiles. Their specially designed annular rings on the shank provide the plastic top pins and with the gripping characteristics of a conventional wood screw. Having a practical polymer shatter proof head together with a stainless steel shank makes these plastic top pins and nails corrosion resistant and maintenance free.
