II. Product Features
1. Dual-function design
Perfectly integrates the knob adjustment and bracket support functions. The knob part can be flexibly adjusted through thread rotation to adjust the spacing between components or the tightening strength; the bottom of the bracket is equipped with an anti-slip structure and a variety of mounting holes, which can be firmly fixed on different planes to ensure the stability of the equipment during operation and effectively improve the adaptability of the use scenario.
2. High-quality materials and processes
Selected high-strength alloy steel or stainless steel as raw materials, after quenching, blackening and other processes, the hardness reaches HRC40-50, the compressive strength exceeds 800MPa, and it has excellent wear resistance and impact resistance. The black coating adopts electrophoresis or spraying technology, has strong adhesion, and has passed the salt spray test for more than 500 hours, and can be used for a long time in harsh environments.
3. Humanized operation experience
The knob surface is designed with anti-slip teeth and adopts ergonomic arc, which is comfortable to hold and can be easily applied even in humid or oily environments. The rotation process is smooth and has scale marks, which can accurately control the adjustment range, greatly improve the operation efficiency and accuracy, and reduce the operation error rate.
4. Rich specification selection

Provide a variety of size specifications to meet the installation needs of different equipment:

Knob diameter (mm)	Bracket height (mm)	Material	Maximum load-bearing capacity (kg)
20	30	Alloy steel	15
35	50	Stainless steel	30
50	80	Alloy steel	50

III. Product Details
1. Material Type
Alloy Steel: 45# steel, 40Cr and other high-quality alloy steels are selected. After quenching and tempering, they have both high strength and good toughness. They are suitable for supporting and fastening equipment in conventional industrial environments and can withstand large mechanical stress.
Stainless Steel: 304 and 316L stainless steel are used. 304 stainless steel has good corrosion resistance and high cost performance, and is suitable for indoor and general corrosive environments; 316L stainless steel has stronger resistance to strong corrosive media such as seawater, acid and alkali due to the addition of molybdenum elements, and is often used in chemical industry, marine engineering and other fields.
2. Size Parameters
Knob Size: The diameter covers multiple specifications of 15mm-50mm, and the thickness is between 5-12mm, which can meet different operating space and strength requirements.
Bracket Size: The height range is 20-100mm, and the bottom support surface is divided into round and square. The size is reasonably adapted according to the height to ensure the stability of the support. The bracket is equipped with M4-M8 specification mounting holes, which are suitable for bolts and nuts of different specifications.
Thread specification: The knob thread adopts the metric standard, including M6, M8, M10, M12 and other specifications, and the thread accuracy reaches 6g level, ensuring smooth screwing and firm connection.
3. Surface treatment
Blackening treatment: Through high-temperature chemical oxidation, a dense black oxide film is formed on the metal surface to enhance the anti-rust ability, which is suitable for industrial scenes with low requirements on appearance.
Electrophoretic treatment: The electrophoretic coating process is adopted, and the coating thickness is uniform (about 15-25μm), with excellent wear resistance, corrosion resistance and adhesion, and the surface is smooth and shiny.
Spraying treatment: Using the electrostatic spraying process, the black powder coating is evenly attached and cured at high temperature to form a high-hardness coating with good scratch resistance. Matte or glossy effects can be customized.
