Design Of Square Set Screws Of Non-metallic Materials

Square set screws of non-metallic materials are mechanical fasteners used to join two objects together. They are made from materials such as plastic, nylon or sometimes ceramic and fiber reinforced polymer. These screws have a square-shaped head that requires a wrench or pliers called a square driver to install and remove them. To design a high-quality square set screw of non-metallic materials, there are some essential criteria to follow. Firstly, the material used must have high mechanical strength, be non-corrosive and durable. The square head should be accurately machined and have a good fit in the mating part to avoid slipping under load. The screw's thread should have a consistent pitch, be deep enough for a secure hold, and have a rolled thread for higher strength. The surface texture of the screw should also be smooth and devoid of any bumps or burs that can lead to weakening of the screw or cause wear of the mating part. Furthermore, the screw's shape should be optimally designed with the correct ratio of thread to shaft diameter to give maximum shear strength. There must also be an allowance for clearance between the screw and the mating part for easy insertion and removal. Additionally, the screw's thread depth, the threads/inch ratio, and the helix angle should be optimized for a reliable grip and excellent torque transmission. In summary, square set screws of non-metallic materials are crucial mechanical fasteners. The design should prioritize high-quality materials, accurate machining of the square head, consistent thread pitch and depth, smooth surface texture, optimal shape with proper thread to shaft diameter ratio, clearance allowance, thread depth, and helix angle.
