Phillips Pan Head Thread Forming Screw for Plastic

SKU: TFS08 Category:

FasPlas Phillips Pan thread forming screws, not to be confused with thread cutting screws, are designed specifically for use with soft materials such as plastic. They are installed in pre-drilled or moulded holes.

  • Phillips Drive
  • 30° thread angle (45° and 60° to order only)
  • Range of diameters and thread lengths
  • Manufactured in steel zinc or zinc & black, as well as stainless steel.
  • Also referred to as self tapping screws for plastic.

The FasPlas Phillips Pan Screw is suitable for fixing into plastic as the 30° thread angle allows the screw to form its own secure engagement with the contact material providing a neat fit and secure resistance without creating any mess and without the need for a drill or other equipment. The Phillips drive prevents the screw driver slipping out of the screw, making it easier to get a secure fit.

FasPlas Phillips Pan Screws are available in zinc steel, black steel and stainless steel in a variety of sizes.
