Black collated drywall screws are specialized screws that have been engineered for the efficient installation of drywall. They are often coated with a black phosphate finish, which not only enhances their rust resistance but also contributes to their aesthetic appeal. The term collated refers to the method in which these screws are packaged and organized, typically in strips or coils. This collating allows for quick and easy installation, particularly when using a screw gun or drywall screw gun, significantly speeding up the process of hanging drywall.

Structural bolts are made from high-strength materials such as grade 5 or grade 8 steel, making them resistant to corrosion and wear. They are heat-treated to achieve the necessary tensile strength, which can range from 120,000 to 180,000 pounds per square inch (psi). This high-strength capacity is crucial for withstanding the dynamic forces and stresses that structures face over time, including wind, seismic activity, and the weight of the structure itself.
