DIN 980 nuts are self-locking nuts with a deformed collar, designed to provide secure fastening even under conditions of vibration or dynamic stress. Their design prevents accidental loosening of the assembly, without the need for washers or additional elements, making them a reliable solution for demanding environments. This type of hexagonal nut maintains constant tightening torque, allowing for a firm and removable assembly without losing effectiveness over time.
Self-locking hex nuts according to DIN 980
At CHAVESBAO we supply DIN 980 nuts in accordance with technical quality standards, available in steel grades 8 and 10, as well as in A2 and A4 stainless steel, ideal for outdoor applications, exposed structures or environments with frequent mechanical vibrations.
Available with finishes such as zinc plating, black or hot-dip galvanising, which reinforce their protection against corrosion, these self-locking nuts are commonly used in machinery, automotive, metal structures and industrial systems that require effective screw locking throughout the service life of the assembly.
