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.

1. Strength and Durability Due to the high-strength material used in their production, M20 bolts can bear heavy loads without deforming or failing, making them ideal for critical structural applications.

2. Sleeve Anchors These anchors have a sleeve that expands as the bolt is tightened. Sleeve anchors are versatile and can be used in both concrete and masonry applications, making them ideal for various construction projects.

1. Structural Support Resin anchor studs are extensively used in construction to provide structural support for beams, columns, and other heavy loads. By securing these components into concrete with resin anchor studs, builders can ensure stability and integrity.

Bracing refers to the methods used to reinforce structures by preventing excessive deformation. In the context of steel beams, bracing typically involves the addition of diagonal members, which connect the main beams to form a triangulated framework. This configuration allows the structure to distribute loads evenly, enhancing its resistance to lateral stress. There are several types of bracing systems, including cross-bracing, K-bracing, and moment-resisting frames, each serving specific structural needs and applications.

Self-drilling galvanized screws are widely used in various sectors, including construction, automotive, and manufacturing. In the building industry, they are commonly employed for securing metal roofing panels, fastening siding, and assembling metal framing systems. The screws are also ideal for use in HVAC systems, where durable and reliable fasteners are crucial for maintaining system integrity.
