Butterfly screws, also known as toggle bolts, are a type of fastener that features a pair of wings that fold during installation and expand once they are inside a pre-drilled hole. The design allows for a stronger grip on hollow walls, such as drywall, where regular screws might not provide sufficient anchoring. Butterfly screws are particularly useful for mounting heavier items like televisions, where the risk of falling can be a significant concern.
There are various types of chipboard fixings available, each designed for specific purposes and applications. Common chipboard fixings include screws, nails, brackets, and connectors. When choosing the right type of fixing for your project, consider the thickness of the chipboard, the weight of the load it will bear, and the environment in which it will be used.
Hex head bolts are a type of fastener characterized by their six-sided (hexagonal) head, which allows for easy gripping and torque application using a wrench. Typically made from materials like carbon steel, stainless steel, or alloy steel, these bolts come in various sizes and grades, each designed to meet specific strength and durability requirements. The hexagonal shape of the head provides a larger surface area for handling, making it easier to achieve the necessary clamping force when tightening.
