Precision-machined connection systems conforming to DIN 3017, SAE standards, and customizable specifications.
In industrial design, the 40mm standard diameter represents a critical mechanical boundary. It is widely used in automotive radiator hoses, turbocharger air pathways, industrial chemical processing pipes, and advanced water treatment system manifolds. This dimension requires precise clamping tension: too low causes catastrophic fluid or pressure leaks, while too high damages soft polymer or rubber hoses.
Our engineering reports indicate a sharp rise in global demand for robust, high-performance sealing systems. Modern systems operate under higher temperatures and pressures, necessitating transitions from traditional carbon steels (W1) to premium grade austenitic stainless steels (W4 and W5).
The market has evolved from simple hardware applications to advanced engineering systems. Heavy machinery, electric vehicles, and smart municipal utilities require connection points that can withstand mechanical stress, dynamic thermal fluctuations, and corrosive media without structural failure.
Our customized quoting models calculate material costs dynamically based on raw material grades, strip widths, and specialized configurations. This helps procurement teams avoid high local distribution premiums and source directly from ISO-certified production lines.

Important considerations for material choice, thread lubrication, and spring-loaded systems.
Most clamps are made of different grades of stainless steel. Usually, customers will use magnets to detect the quality of the material. If there is magnetism, the material is not good. In fact, the opposite is true. Magnetism means that the raw material has high hardness and high strength. Because the currently made clamps are usually made of austenitic stainless steel such as 201, 301, 304, and 316, after heat treatment, the raw materials can be completely non-magnetic, but the raw materials used to produce the clamps must meet the hardness and tensile strength of the product itself. So the hardness and tensile strength can only be met by the cold rolling process, which requires the soft material to be rolled into a thinner cold-rolled strip. After cold-rolling, they will indeed become harder and also generate a magnetic field.
At present, the galvanized layer on the surface of carbon steel plated screws plays a lubricating role. Most steel screws in DIN3017 clamps are also galvanized, which can play a lubricating role. If you do not need zinc plating, you need wax compound as a lubricant. At any time, the wax compound will be dried, the temperature during transportation or the harsh environment will cause the loss, so the lubrication will decline, so it is recommended that the steel screw is also galvanized.
T-bolt clamp with spring are commonly used in heavy truck coolant and charge air systems. The purpose of the spring is to mediate the expansion and contraction of the hose connection. Therefore, when installing this clamp, you must pay attention to the end of the spring can not be completely down. If there are exactly two problems in the end: one is that the spring loses its function of mediating thermal expansion and contraction and becomes a solid spacer; although this may shrink somewhat, there is absolutely no way to adjust to thermal expansion and contraction. The second is the heating of the fastening system, the hose will have excessive fastening pressure, damage the pipe fittings, and greatly reduce the service life of the fastening system.
At present, the factory has sufficient raw materials, all of which are from well-known domestic manufacturers. After each batch of raw materials arrives, our company will test the entire material, hardness, tensile force, and size. Once qualified, they will be put in the raw material warehouse.
This raw material testing step helps prevent defects in our forming operations and ensures that the final assembly meets the designed clamping force values.
At present, our company has 8 technical personnel (including 5 senior engineers), has the ability to develop new products, has its own abrasive processing center. Technical problems before and after sales can be answered by senior engineers.
