3 point self drilling screw

The efficiency of steel shear studs lies in their design. Their compact size allows for a large number to be installed in a small area, maximizing load-bearing capacity. Moreover, they offer advantages such as ease of installation, cost-effectiveness, and the ability to resist both tension and compression loads. This versatility makes them ideal for various applications, including floor slabs, beams, and columns in buildings, bridges, and other infrastructure projects.

The self-tapping property of these screws lies in their thread design. The sharp cutting edges on the screw's thread cut into the material, creating a mating thread as it is screwed in. This mechanism ensures a secure grip, minimizing the risk of stripped threads or loose connections. Moreover, due to their plastic composition, nylon self-tapping screws can be easily removed and reinserted without damaging the surrounding material, a characteristic that metal screws often lack.

Secondly,the desired holding power is another important factor to consider when selecting the correct wedge, bolt, and drill size. The holding power of a fastener is determined by its diameter, length, and thread pitch. Generally speaking, larger fasteners with higher thread pitches provide greater holding power. However, it's important to ensure that the fasteners you select are appropriate for the thickness of the material being fastened. If the fasteners are too large for the material, they may not be able to penetrate the material fully, resulting in reduced holding power.
