Cage Nuts Manufacturer & Supplier

Our cage nuts are an innovative blend of a nut and a spring steel clip. The design, reminiscent of butterfly wings, allows for quick and effortless adjustment of the workpiece when installed in square or rectangular holes. These nuts can automatically correct offset hole positions and prevent rotation during locking. We offer these components in two materials: Cage: High carbon steel or stainless steel; Nut: Low carbon steel or stainless steel.

Push Nuts Manufacturer & Supplier

We also manufacture a wide variety of push nuts that integrate the features of a washer and a nut. They stand out for their locking mechanism, as the toothed plate exerts pressure on the mating parts to create an anti-loose effect. Their design, lacking threads and grooves, enables quick assembly, and once fixed, they are difficult to remove or damage.

We provide different types of push nuts such as:

Round / Round Flat Push Nuts (also known as Star-lock Washers)

Please provide the specifications and quantity of the screws you need. Specifications should include material, surface treatment, head type, driver type, thread type, point type, and dimensions (Metric, Imperial, US).

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.

Our products are certified by ISO 9001, which is an international standard for quality management systems. This certification ensures that we adhere to best practices for producing high-quality products that meet our customers’ expectations and requirements.

Some of our products also have CE certification, which is a mark that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area. Please contact us for CE-certified products.
