C510 Bronze Nut, Hex Bolts, Screw and PB washers manufacturer in India
We are a leading Phosphor Bronze Fasteners Suppliers and we are in the business for several years now. Great Steel & Metals is known for the high quality products in the phosphorus bronze material. Our Phosphor Bronze Bolts and Nuts are made up of the phosphor bronze which is a copper based alloy. The composition has copper, tin, phosphorus and other elements in trace amounts as well. We produce ASTM C54400 Screws that are tough, strong and have low coefficient of friction. The operation with screws and bolts of this grade of material is easier because the products are cleaner and do not produce grain boundaries in case of welding. The Uns C51900 Threaded Rod is used in bushings and bearings making and the C54400 Bronze Studs are used in other strong and corrosion resistant parts of different applications such as the dental equipment. The material has high corrosion resistance, wear and tear resistance and resistant to fatigue as well. Therefore, the Phos Bronze Hex Bolt is a preferred choice to be used in applications that require toughness, wear and tear resistance and fatigue resistance. The material is also highly electric conductive. It can be used in electrical circuits and wirings. The C54400 Phosphor Bronze Allen Cap Screw is a special type of screws operable with Allen keys that are used in specific applications; usually in the narrow spaces of electrical applications. The Phosphor Bronze Spring Socket Cap Screw has an additional grip and the 510 Phosphor Bronze Hex Screws are stronger. We produce all kinds of bolts and nuts of this grade and you can contact us for pricing.
