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.

2. Corrosion Resistance Many manufacturers provide M20 bolts with coatings or treatments (like galvanization) to enhance corrosion resistance. This is vital for outdoor and industrial applications where exposure to moisture and chemicals is common.

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.
