Due to the unique properties of plastic, the screws used to make connections in this material must also have special properties. The process of threading plastic with a screw is different than threading wood with a screw. It takes the right screw to penetrate the surface of plastic and achieve the desired clamping results. At ITW Shakeproof Industrial, we are your source for an array of thread forming screws for plasticand metal.
No tap is required with a thread forming screw. This screw produces the required threads as it enters and moves deeper into the material.
Regardless of whether you need to use micro or regular screws, the below information will help you choose the right screw for your plastic material connection.
Plastite Screws
These plastite screws are created with widely spaced threads that allow the screw to easily drive into the plastic material. They are suitable for use with soft and hard plastics. The space between the threads of these thread forming screws for plastic helps keep these screws in position and lessens the problem of loosening due to vibration.
PT Screws
With sharp threads, PT screws can drive into plastics with ease and without causing flakes. Because the thread angle reduces the problem of vibrational loosening, these screws remain secure in place. The design of these screws resist relaxation over a period of time which is a problem with screws that do not secure plastic with the same tightness.
Delta PT Screws
One step higher than PT screws, Delta PT screws provide even greater holding power and flake reduction capabilities. These screws have threads with a lower angle that displaces the plastic to a greater degree.
P-Type Screws
These P-type screws have larger spaces between their threads. They typically have a wide thread-cutting slot and edge. As a result, chips do not get trapped between the threads, enabling the screw to cut through the plastic material freely without causing a major fracture.
Hi-Lo Screws
With smaller diameters, hi-low screws produce smaller holes in plastic. These screws are made with double threads at a 30 degree angle. This is the optimal angle for producing positive thread engagement and minimizing the displacement of material.
If the options provided above are not satisfactory, customized screws are an option. With a customized screw you can ensure your products are manufactured for long terms durability and service.
