Socket Set Machine Screws in Standard & Custom Configurations

Socket set screws are typically headless and fully threaded, allowing them to secure one object against or within another effectively. This feature makes them ideal for applications such as fastening a gear or pulley to a shaft. Their headless design means that they don’t protrude beyond the diameter of the screw thread, contributing to a sleek and efficient design.

There are a variety of point types available for socket set screws. These various tips cater to a range of engineering needs, whether it’s the precision flat contact of a flat point or the targeted stress of a cone point. The most commonly used point type is the cup point due to its rounded surface area that offers a strong grip without overly concentrating stress. Knurled cup points add an extra layer of security, providing a locking action that makes them perfect for high-vibration applications, like certain types of machinery.

Socket set screws are designed with sturdiness and longevity in mind. These screws feature forged sockets for maximum strength and resistance against corner cracking. The socket walls are stronger than those created by the drill and broach method, lessening the potential for failure. A prime example of their application is the cup point screw, which provides a fast and relatively permanent location for pulleys, collars, and other components on shafts.

Common Screw Materials

Choose based on the product’s intended use, application method, and customer requirements.

Stainless Steel:

Commonly used types include SUS302, SUS304, SUS316, SUS410. A special type called NSSC550 is exclusive to Cheng Hao, which has high hardness, high corrosion resistance, and high acid resistance. Its rust prevention is 15 times better than existing materials for screws.

Carbon Steel:

Low carbon steel, medium carbon steel, high carbon steel.

Alloy Steel:

Refers to steel materials that, besides containing carbon, also have other alloying elements such as silicon, manganese, chromium, nickel, vanadium, molybdenum, etc.

Aluminum Alloy:

Common material codes include 2011, 2024, 6061, 6082, 7075.


Brass (Yellow brass), Bronze.

Customization is our forte. You can provide us with diagrams, design drawings, or a list of requirements, and our expert team will provide a quote based on your specifications.

Send us your design

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.
