Design Of Self-tapping Non-metallic Bolts

Self-tapping non-metallic bolts are a type of fastener designed to be used in situations where traditional metallic bolts cannot be used effectively. These bolts are made from materials like plastic or composite and possess a unique design that allows them to create their own threads as they are screwed into a surface. Designing self-tapping non-metallic bolts requires attention to several critical factors. Firstly, the bolt must be made of a strong and durable material that can withstand the load and stresses it will be subjected to. Secondly, the design of the bolt thread must be carefully considered, ensuring it is optimised for the type of material it will be screwed into. Another important aspect of designing this type of bolt is the head design. It must be designed to fit the application type, and the right size and shape must be chosen to offer the best grip and anchoring to the surface. Additionally, design considerations must be made for type and height of flutes and corners of the bolt. The design must allow for adequate space for the material to be displaced into the area created by the thread when the bolt is driven into the material to minimise the likelihood of a crack or fracture developing. Lastly, designers of self-tapping non-metallic bolts must consider the length of the bolt to ensure it penetrates sufficiently depth to secure itself to the surface.
