Collar nut M8 is a hexagonal nut with an additional collar at the base, which protects against self-loosening and unscrewing. This type of nuts are perfect for the most demanding and precise connections such us, assembling aluminium profiles, frames of 3d printers or CNC machines, as well as various types of general purpose constructions in industry. They are covered with a galvanic zinc coating, which gives high mechanical durability and resistance to corrosion.
