• Thread Rolling Screws for Plastics. It has a triangular cross-sectional form that reduces thread forming torque and radial stress. The screw also has a twin-lead thread that improves stripping and increases friction. The sharp 48° thread profile increases holding strength and reduces material displacement and boss bursting tendencies. The flat crest lead thread helps align the screw and displace material during thread forming.
