The rubber washer plays a crucial role in this assembly. Made from durable and resilient materials, such as neoprene or silicone, it offers excellent compression and sealing properties. When tightened, the rubber washer compresses between the screw head and the surface it's fixed to, creating a waterproof and airtight seal. This is particularly beneficial in situations where leakage or environmental elements need to be kept at bay, such as in roofing, plumbing, or automotive applications.

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.
