Thread-Forming Screws For Plastics

These thread-forming screws for plastics are designed to form clean internal threads with most materials such as ABS, nylon, polypropylene, and other molded resins. Instead of removing material, they compress it to form stable threads with good holding power, which can improve repeatability on production lines. The key is selecting the right screw geometry and using properly sized pilot holes so the plastic does not split or cold-flow under load. These fasteners are commonly used in housings, covers, appliance components, electronics, and consumer products where you need serviceable joints without inserts. If you want a dependable alternative to other branded options, Fastener SuperStore carries the generic alternatives to PLASTITE® that support reliable fastening in many plastic grades while maintaining consistent thread engagement over repeated assembly cycles.

Thread-Forming Screws For Metals

Thread-forming screws for metals are used when you need strong threads in thin sections without cutting chips or dealing with secondary tapping operations. They form internal threads by cold working the material, which can increase strength around the hole and improve pullout resistance compared to some cut-thread methods. These are commonly specified for sheet metal, light-gauge components, and many steel assemblies where consistent torque and clamp load matter. Hole sizing is critical: the correct pilot hole diameter helps manage driving torque and protects the part from distortion. Fastener SuperStore offers generic alternatives to TAPTITE® for applications that require reliable, repeatable fastening in metal without sacrificing thread engagement or assembly speed. They’re also helpful for high-volume production lines where cycle time, consistency, and clean work areas matter.

High Low Thread-Forming Screws

High low thread-forming screws use alternating high and low threads to reduce driving torque while improving grip in softer substrates. This design helps the screw start smoothly, form stable threads, and resist loosening from vibration. They’re commonly used in plastics, wood-based materials, and certain light metals where a standard thread profile can strip out or crack the part. With the right pilot hole, the high threads engage firmly while the low threads relieve pressure, helping the assembly stay tight without overstressing the material. High low designs are also useful when parts are assembled and serviced more than once, since the formed threads can remain more consistent over time. If you need a thread-forming screw that balances easy driving with dependable holding, this category is a solid place to start.
