About Special Screw
At Bhagwati Enterprise, Special Screws are designed and manufactured to deliver reliable performance in a wide range of industrial applications. These screws are often used in Screw-Barrel configurations and are available in multiple sizes and specifications to suit different machinery requirements. Our manufacturing process focuses on high dimensional accuracy, ensuring that every screw is produced with precision and strict quality control.
Special Screws manufactured by Bhagwati Enterprise are commonly used in blow moulding machines, cable and wire processing machines, food processing equipment, and mixing machines. The diameter and length of these screws can be customized based on the specific needs of customers and their machine configurations. Advanced machining and finishing equipment are used during production to ensure a smooth surface finish, improved abrasion resistance, and long operational life.
To achieve superior strength and durability, Special Screws are manufactured using high-grade materials such as EN41B and EN19 steel. These screws undergo nitriding and specialized coating processes, enabling them to achieve surface hardness levels of approximately 62–65 HRC. Bhagwati Enterprise offers Special Screws in diameters ranging from 14 mm to 150 mm, with lengths available up to 4.5 meters, ensuring reliable performance in demanding industrial environments.
