Pozi countersunk thread forming screws are ideal for installation into a pre-drilled or moulded hole in softer materials such as plastic. These screws are available with 30°, 45° and 60° degrees thread angles, with the latter two featuring a trilobular body, giving a wider choice to suit a variety of applications. Using an angled thread allows for a better and cleaner mating with the contact material when forming the thread engagement, and a better resistance to ensue a more secure fit. This in turn leads to a high pull performance ensuring that the screws stays in position.
