Racket screws, also known as toggle bolts, are a type of fastener that is commonly used in applications where a strong hold is required in hollow walls or ceilings. They consist of a long bolt with spring-loaded wings that fold back as the screw is inserted into a pre-drilled hole. Once the screw is tightened, the wings expand behind the wall, providing a secure anchor point for the screw.
Racket screws are available in various sizes, ranging from small to large, with different weight capacities depending on the size and material of the screw. They are typically made of steel or zinc-plated steel.
Fields of application for racket screws include:
*Construction and building projects: They are commonly used to secure fixtures and fittings, such as shelves, cabinets, and light fixtures, to drywall or plasterboard walls.
*DIY and home improvement projects: They are useful for hanging mirrors, picture frames, and other decorative items on walls.
*Industrial and commercial applications: They are used to secure equipment and machinery to walls or ceilings.
When selecting racket screws, it is important to choose the right size and weight capacity for the specific application. The length of the bolt should be long enough to extend past the thickness of the wall, while the wings should be able to expand fully behind the wall to provide a secure hold.
Overall, racket screws are a versatile and effective fastener for a range of applications. Their ability to provide a strong hold in hollow walls makes them a popular choice in construction, DIY, and industrial settings.
