Our line of carbon steel fasteners is designed to meet the high-strength connection demands of various industrial and construction applications. Known for their exceptional durability and reliability, these fasteners ensure secure, reliable fastening in a variety of harsh environments.We offer a wide variety of products, including:Nuts: We offer a variety of sizes, including 5/16-18 thread and 1/2-13 thread American standard nuts, as well as the popular M12 metric nut, to accommodate various bolt sizes.Screws and Bolts: We offer universal hexagonal screws and half-thread hexagonal screws. The hexagonal design facilitates wrench installation and removal, while half-thread bolts offer a balance of strength in the connection area and smoothness in the non-connection area.Nuts: We offer American standard flat nuts and nylon lock nuts. American standard flat nuts offer a wide contact area for better pressure distribution. Nylon lock nuts feature an internal nylon ring to prevent loosening due to vibration and provide additional security.All fasteners are made of high-quality carbon steel and precision-machined to ensure precise dimensions and a smooth surface. They are widely used in machinery and equipment, furniture manufacturing, building structures and the automotive industry, and are your reliable connection solutions.

A rolling bearing is a mechanical component that supports rotational motion by rolling elements (such as steel balls, rollers, or needles) rolling between two rings. Its primary function is to reduce friction between rotating parts and transmit loads.Unlike plain bearings, rolling bearings utilize rolling friction, resulting in a very low coefficient of friction and low starting resistance. This has led to their widespread use in various mechanical devices, such as automobiles, motors, machine tools, and household appliances.Based on the shape of the rolling elements, rolling bearings can be divided into several types, including deep groove ball bearings and angular contact ball bearings, which use steel balls, and cylindrical and tapered roller bearings, which use rollers. Each type has its own specific structure and application scenarios, meeting varying speed, load, and precision requirements.

Made of sturdy steel and featuring a reinforced structure, the trolley withstands high operating pressure and resists deformation. Durable, industrial-grade casters ensure smooth and flexible mobility on any surface, making it easy to push even a fully loaded load.The trolley's most notable feature is its innovative folding function. When not in use, the handle and base can be easily folded up in a few simple steps, significantly saving storage space. Whether stored in a corner of a garage, warehouse, or tool shed, it takes up minimal space.The trolley's ergonomic handle provides a comfortable grip, ensuring fatigue-free handling even during extended periods. Whether you're moving home, performing logistics distribution, or transporting materials within a factory, this heavy-duty folding steel trolley is a great, efficient and labor-saving tool.
