Thread Forming Screws for Plastics

At Crown Screw we understand the critical role that our thread forming screws for plastics play in the manufacture of your products. From high volume automotive customers, local fabricators, moulders to low volume prototyping, we will have the precise components for your requirements. This information page is designed to give you a brief overview into the world of thread forming screws, to guide you towards the right component for your project.

Thread Forming Screws

Our range of thread forming screws provide a fast, efficient and cost-effective way to clamp multiple plastic work pieces together. This range of screws has specifically been designed to outperform standard self-tapping screws. The form and angle of the thread optimises performance by forming a thread in the pre-drilled pilot hole, rather than cutting a thread using a standard self-tapping screw. The pre-drilled pilot hole diameter will differ depending on the hardness of the mating material, allowing perfect formation and torque in a wide range of plastics. Due to the design of the threads these screws can be driven in/out on multiple occasions before you will start to see a change in performance. Perfect for items that will need to be opened/closed on more than one occasion. Most commonly used in the automotive, electronics, medical and injection moulding industries, these are available in various thread sizes, materials and finishes. In need something a little more special to suit your application? We can manufacture to your specific specification. Our thread forming screws provide a simple, efficient and cost-effective way to have the ability to screw directly into plastics, enabling clamping and assembly of different materials. This range of screws has specifically been designed to outperform standard self-tapping screws. The form and angle of the thread optimises performance by forming a thread in the pre-drilled pilot hole, rather than cutting a thread using a standard self-tapping screw. The pre-drilled pilot hole dimeter will differ dependant on the hardness of the mating material, allowing perfect formation and torque in a wide range of plastics. Due to the design of the threads, these screws can driven in/out on multiple occasions before you will start to see a change of performance. Perfect for items that will need to be opened/closed on more than one occasion. Most commonly used in the automotive, injection moulding, electrical industries and are available in various head styles, drive styles, lengths, materials and finishes. If a special is required, we can manufacture to your specific requirements.
