Tek screws are designed with a unique combination of materials and manufacturing processes that ensure their superior performance. They are typically made from high-grade steel, which provides the necessary strength and resilience to withstand various environmental conditions and demanding applications. The screws are then subjected to a heat treatment process that enhances their hardness and resistance to corrosion, further extending their lifespan.

Black phosphate drywall screws are specialized fasteners designed specifically for the installation of drywall and related materials. They are characterized by a unique black phosphate coating that not only enhances their aesthetic appeal but also provides increased corrosion resistance. This coating is produced through a chemical process that creates a layer of iron phosphate on the screw's surface. This is crucial in construction environments where exposure to moisture and varying temperatures can lead to rust and degradation of standard screws.
