8 tek screws

The head of a self-drilling screw is typically made from nylon, a synthetic polymer known for its durability, resilience, and resistance to chemicals. This material choice serves several purposes. Firstly, the nylon head provides an excellent grip, reducing the chances of slippage during tightening, making it ideal for applications where a secure hold is essential. Secondly, nylon is non-conductive, making these screws safe to use in electrical installations. Lastly, the low friction coefficient of nylon allows the screw to glide smoothly into the material, minimizing the risk of damage.

One of the most significant advantages of chemical anchor fasteners is their high load-bearing capacity. Unlike traditional mechanical anchors, which can be limited by the tensile and shear strength of the materials they penetrate, chemical anchors distribute loads more evenly across a larger surface area. This is particularly beneficial in applications where heavy loads are expected, such as in building facades, heavy machinery installations, or structural reinforcements.
