Product Description

The Premium Stainless Steel Expansion Hook is a remarkable device designed for the purpose of fastening and hanging objects with precision and strength. Crafted from high-grade stainless steel, it offers exceptional resistance to corrosion and boasts robust durability.
Here is a detailed description of it, showcasing its superior features and benefits:

Structural Characteristics

Expansion Tube: Engineered with a cylindrical form and constructed from premium stainless steel, the expansion tube features an outer diameter slightly larger than the installation hole. Through strategic cuts or gaps, when the screw is inserted, the tube expands outward, securely adhering to the hole's wall with unmatched stability.

Screw: As the core component of the expansion hook, the screw secures the expansion tube within the hole. Its head is meticulously designed, typically hexagonal or cross-shaped, enabling easy tightening with a wrench or screwdriver, ensuring unmatched reliability.

Hook: Elegantly connected to one end of the screw, the hook is tailored for hanging objects. Available in various forms such as straight, curved, or sheep-eye shapes, it adapts to diverse requirements, delivering versatility and functionality.

Working Principle

The operational essence of stainless steel expansion hooks lies in the expanding capability of the expansion tube. Once the screw is driven into the tube, the threads compel the tube to expand outward, ensuring perfect contact with the hole's wall. The resulting frictional force steadfastly secures the hook in place. For hanging, simply position the object on the hook for instantaneous stability.

Specification Parameters

Thread Specifications: Widely used thread options include M6, M8, M10, M12, with 'M' representing metric threads and the succeeding number indicating the nominal thread diameter.

• Length Range: The available length dimensions are diverse, ranging from 20mm to 100mm, offering customization to suit specific requirements for each application.

• Other Parameters: Beyond thread specifications and length, additional factors such as hook shape, opening size, and load-bearing capacity are crucial. These parameters are variable to accommodate different specifications and application scenarios, ensuring versatility.

Materials and Surface Treatment

Material: Constructed primarily from stainless steel grades such as 304 and 316, these materials ensure unparalleled corrosion resistance, strength, and longevity, making them apt for a variety of environments.

Surface Treatment: Enhancing both corrosion resistance and aesthetic appeal, surface treatments like polishing, chrome plating, and nickel plating are applied. These methods not only render the hook's surface smoother and more lustrous but also elevate its resistance to corrosion.

Application Area

• Building Decoration: Stainless steel expansion hooks play a vital role in building decoration, adeptly supporting lamps, curtains, picture frames, and air conditioning outdoor units. Their design allows easy installation on walls, ceilings, or structures without requiring complex tools.

Household Goods: Widely favored in domestic settings, these hooks are perfect for organizing kitchen utensils, bathroom essentials, clothing, and more, maintaining a neat and orderly home environment.

In the Industrial Field: A trusted choice for securing mechanical equipment, pipelines, and cables, stainless steel expansion hooks provide solid connections and fixtures, ensuring optimal operational safety and reliability.
