Citizen Metals manufactures a wide variety of nuts. Nuts can be utilised for numerous purposes. For bolts, nuts are employed. There are various sizes, qualities, and shapes of nuts available. Citizen Metals manufactures and exports industrial nuts of superior quality. We ship nuts including hex nuts, flange nuts, square nuts, t nuts, lock nuts, and nylock nuts. We are a well-known exporter of industrial square nuts in Mumbai. A square nut is a fastener that is threaded. To secure multiple components together, square nuts are almost always paired with a bolt. The two partners are held together by a combination of friction (with minimal elastic deformation), bolt stretching, and piece compression. When the maximum amount of torque and grip for a particular size is required, square nuts are now utilised. Citizen Metals specialises in the manufacture and export of premium square nuts.
