1. Self-Drilling Tek Screws These screws come with a drill point that allows them to penetrate and create their own pilot hole in concrete and masonry. They are ideal for fastening materials like metal, wood, or plastics to concrete surfaces.
5 8 wedge bolt. For example, in the assembly of large structures such as bridges or buildings, wedges may be used to initially separate components while bolts are tightened to ensure a secure connection. This approach not only enhances the efficiency of the assembly process but also improves the overall structural integrity of the finished product.

Fine thread screws should be long enough to offer sufficient grip while avoiding penetration too deep into the material, which could cause damage. A general rule of thumb is to select screws that penetrate at least 1 inch into the wood.
