butterfly screws. They can be made from various materials, including steel, stainless steel, brass, aluminum, or plastic, catering to different load-bearing requirements, corrosion resistance, or aesthetic preferences. Additionally, they come in different sizes and thread types, allowing for adaptability to numerous applications.4. Resistance to Corrosion Many metal expansion nuts are available in corrosion-resistant materials, such as stainless steel or coated metals, which are ideal for outdoor or humid environments.
Heavy-duty expansion anchors are mechanical anchors that create a secure hold by expanding within a drilled hole in concrete or masonry. As the anchor is tightened, the anchor body expands against the walls of the hole, ensuring a tight grip that can safely hold heavy loads. These anchors come in various materials, including steel and stainless steel, which are chosen based on the environment and load requirements.
1. Corrosion Resistance The black finish provides a barrier against moisture and environmental factors, significantly reducing the risk of rust and degradation.
