1. Corrosion Resistance One of the primary advantages of black phosphate drywall screws is their superior resistance to corrosion. Unlike traditional screws, which are often susceptible to rust, the phosphate coating acts as a buffer against humidity and other environmental factors. This is particularly beneficial in regions with high humidity levels or where drywall installations are commonly subjected to moisture.

Applications

Hex head self-drilling screws, often referred to as Tek screws, are designed with a hexagonal head that allows for easy tightening using a wrench or a socket. The self-drilling feature means that these screws come with a drill bit tip that can penetrate metal, wood, and other materials without the need for pre-drilled holes. This eliminates the need for additional tools, making installation faster and more efficient.
