Professional Applications & Engineering Value

These No. 6 plastic tapping screws are engineered specifically for plastic fastening applications where traditional fasteners fail. The TRS thread forming design with tri-lobe shank cross-section displaces plastic material to create strong, permanent threads without cutting or creating chips. This thread forming method eliminates the need for threaded inserts while providing superior resistance to vibration loosening. The Black-Oxide Steel construction combined with T15 Torx drive ensures maximum torque transmission during installation, reducing the risk of head stripping and assembly errors. Ideal for plastic assembly in electronics enclosures, automotive components, and consumer products where reliable, long-lasting fastening solutions are critical for product integrity and performance.
