What are NSSC 550 Screws & Where are They Used?

NSSC 550 screws are high-strength, heat-treated screws that are used in a variety of applications where high tensile strength and fatigue resistance are required. NSSC 550 screws provide excellent strength and corrosion resistance.

NSSC 550 screws are the product of choice for structural applications like bridges and buildings, where high strength and fatigue resistance are needed. They are also used extensively in machine tools, where both strength and vibration resistance are vital. for their ability to withstand harsh environmental conditions.

NSSC 550 screws, with their high tensile strength, surpass standard steel screws, making them perfect for high-load applications. Additionally, their outstanding fatigue resistance enables them to endure repeated loading and unloading, making them ideal for dynamic load scenarios. Their corrosion resistance makes them perfect for harsh environments so they are used extensively in heavy engineering projects.

The MOQ varies depending on the material. As a professional screw manufacturer, our MOQ is 50,000 pieces for stainless steel and 100,000 pieces for carbon steel. This requirement, which may seem high to some customers, is designed to ensure product quality, cost-effectiveness, production efficiency, and shipping efficiency, and to pass on price benefits to customers. For special-purpose screws or orders with a high total quantity, we also support a lower MOQ, making cooperation very convenient.

Carbon steel screws will rust when exposed to moisture unless they are coated with an anti-rust coating or made of stainless steel. However, if the anti-rust coating is worn or chipped due to external factors, thereby reducing its anti-rust strength, rust may occur under the coating. Stainless steel screws are the most resistant to rust and corrosion. Although they are more expensive, their rust resistance is not easily reduced because the entire structure of the screw is stainless steel.
