A cap screw is a high-strength threaded component that serves as a joining means for two or more components in heavy-duty applications in various types of machines. This type of bolt is not the same as regular bolts since it comes with precise threads and is either screwed into a tapped hole or used with a nut, according to the type of its usage. It finds application in vehicles, mining, railways, construction, earthmoving and other machines requiring reliable fastening.
Cap screws are made from high-quality alloy steel, and there are various grades, such as grade 12.9, which provides high tensile strength, load-carrying capacity and long service life under harsh operating conditions.
Cap screws find their application in various heavy-duty fastening operations where strength and precision are vital.
