Expansion Bolts For Concrete

Expansion Bolts For Concrete is a special fastener used to fix equipment and components, widely used in construction, bridges and other engineering projects. Its working principle is to achieve bolt anchoring through the expansion effect of expansion sleeves in concrete or brick masonry walls, foundations, and other anchoring bodies. Expansion Bolts For Concrete are usually composed of an expansion bolt sleeve and a bolt. When the nut is tightened, the bolt stretches outward, causing the expansion sleeve to expand and embed into the concrete, thereby achieving a fixed effect. The specifications of Expansion Bolts For Concrete are usually expressed in terms of their shaft diameter, commonly ranging from M2 to M24. They are suitable for use on ordinary concrete and can be made of carbon steel, alloy steel, or stainless steel. The design Expansion Bolts For Concrete allows for installation without the need for pre drilling, making them more economical and efficient during construction.
