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.
