DURO PT® SCREW

The Duro-PT® SCREW is a direct screw fastener for use in thermosetting plastics.
The design incorporates many unique features which provide designers with a really effective direct screw fixing for these materials. The cutting notch combined with the profiled thread root and special thread form provides low installation and high stripping torques.

The efficient removal of cutting debris ensures greatly reduced bursting forces, providing the solution to a common problem associated with conventional self tapping screws, when used in thermosets.

• Type of thermoset material used
• The density of the material
• The amount and type of filler
