Product Description

Class 4.8 Colored Zinc Internal Expansion Implosion Iron Galvanized M8M12M16 Extended Expansion Screws Bolts

Expansion screws, also known as expansion anchors or toggle bolts, are a type of fastener used to secure objects to surfaces that may not be able to support the weight or load directly. They provide a secure attachment by expanding and gripping the material behind the surface when tightened.

Here are some key features and characteristics of expansion screws:

  1. Design: Expansion screws typically consist of a threaded screw and a separate anchor or toggle mechanism. The anchor is inserted into a pre-drilled hole in the surface, and the screw is threaded into the anchor to create a secure connection.

  2. Toggle Mechanism: The anchor or toggle mechanism is usually made of metal or plastic and has wings or arms that fold or collapse to fit through the pre-drilled hole. Once the anchor is inside the material, the wings or arms expand or open up, creating a larger surface area for gripping and providing stability.

  3. Installation: To install an expansion screw, a hole is drilled into the surface, and the anchor or toggle mechanism is inserted into the hole. The screw is then threaded into the anchor, which causes the wings or arms to expand behind the surface, securing the screw and creating a strong hold.

  4. Material and Finishes: Expansion screws are commonly made from materials such as steel, stainless steel, or other alloys, chosen for their strength and durability. They can also be coated or plated with finishes like zinc or other corrosion-resistant coatings to enhance their longevity.

  5. Load Capacity: The load capacity of expansion screws depends on several factors, including the size of the screw, the strength of the anchor or toggle mechanism, and the quality of the material being anchored. It is important to choose expansion screws with appropriate load ratings for the specific application to ensure a secure and safe installation.

  6. Applications: Expansion screws are commonly used in construction, woodworking, and DIY projects to secure items such as shelves, cabinets, light fixtures, and other objects to drywall, plaster, or hollow surfaces. They are particularly useful when dealing with materials that cannot support heavy loads on their own.

  7. Removability: Expansion screws can be removed by unscrewing them from the anchor. However, it may be necessary to replace the anchor if the hole is enlarged or damaged during removal.
