Discover the comprehensive details that highlight the superior features and benefits of this exceptional product:

Structural Characteristics

Expansion Tube: Crafted in a precise cylindrical form, this component is made from durable stainless steel, with an outer diameter slightly exceeding the intended installation hole size. Ingeniously designed cuts or gaps allow the tube to expand outward when the screw is introduced, creating a secure and snug fit against the hole wall for unparalleled stability.

Screw: Serving as the pivotal element of the expansion hook, the screw secures the expansion tube in position. Its head is engineered in hexagonal or cross shapes, facilitating seamless tightening with a wrench or screwdriver, thus ensuring a steadfast hold.

Hook: Seamlessly integrated with one end of the screw, the hook is expertly designed for hanging a variety of objects. Available in diverse forms such as straight hook, curved hook, or sheep eye hook, it caters to versatile usage requirements, enhancing convenience and practicality.

Working Principle

The ingenious functionality of stainless steel expansion hooks capitalizes on the expansion tube's characteristics. As the screw threads into the expansion tube, it prompts the tube to expand outward, establishing a firm contact with the hole wall. This action generates a robust frictional force, effectively anchoring the expansion hook securely in place. To utilize, simply suspend the desired object upon the hook for secure holding.

Specification Parameters

Thread Specifications: Commonly available in M6, M8, M10, M12, etc., where 'M' denotes metric threads and the number specifies the thread's nominal diameter, offering precision and adaptability for diverse applications.

• Length Range: Featuring a versatile range of lengths, typically from 20mm to 100mm, allowing customization to suit specific needs and ensuring optimal performance in any scenario.

• Additional Parameters: Beyond threads and lengths, stainless steel expansion hooks present varied parameters such as hook shape, opening size, and load-bearing capacity, tailored to meet the demands of different specifications and application settings.

Materials and Surface Treatment

Material: The core composition includes premium stainless steels like 304 and 316, renowned for their outstanding corrosion resistance, strength, and durability, making them ideal for prolonged use across diverse environments.

Surface Treatment: To enhance both aesthetic appeal and corrosion resistance, processes like polishing, chrome plating, and nickel plating are employed, ensuring the expansion hook's surface remains smooth, shiny, and resilient against corrosion.

Application Areas

• Building Decoration: Widely utilized in construction decor, these hooks are perfect for suspending lamps, curtains, picture frames, and outdoor air conditioning units. They enable easy and secure installation onto walls, ceilings, or structures without complex tools, saving time and effort.

Household Goods: In home settings, stainless steel expansion hooks prove invaluable for organizing kitchen utensils, bathroom essentials, clothing, and more, contributing to a tidy and orderly home environment.

In industrial sectors, these hooks are integral for securing mechanical equipment, pipelines, and cables, providing reliable connections and stability to ensure equipment operates safely and efficiently.
