Size & Type: #4-20 x 3/8 in; Thread rolling screw (self-tapping) designed for plastics and light-metal assemblies; an excellent alternative to Plastite screws.

Key Benefits: Strong, form-fit threads that resist loosening, easier driving with lubricated wax, and superior performance in plastic substrates thanks to the thread-rolling process that creates durable, uniform threads.

Recommended Uses: Fastening plastic components, enclosures, dashboards, trim, and other assemblies where a flush head and secure, vibration-resistant joint are needed.

Why choose these screws

Designed to deliver consistent, long-lasting performance in plastic and light-metal applications, these screws leverage a thread-rolling process to form durable threads without requiring pre-cut threads. The lubricated wax coating reduces friction during installation, enhancing drive feel and reducing cam-out for precise, repeatable assemblies.
