Plastite® 60-1 Fasteners

Screws For Plastic And Other Low Density Materials

Plastite trilobular thread rolling screws are designed for high performance fastening in a wide range of thermoplastics. The 60° profile on the Type 60-1 screw penetrates deeply into the work piece, absorbing higher torques without stripping and resisting pullout forces. As threads are formed, the plastic material recovers and fills in around the tri-lobular threads, providing resistance to loosening and assuring a secure assembly.
