Wafer head screws are distinguished by their low-profile, flat heads, which provide a sleek finish and minimize protrusion above the surface. The designation 1% 201% 4% refers to specific mechanical and material properties that make these screws particularly effective in certain applications. The combination of these percentages generally relates to the composition of the screw materials and their tensile strength.

Drywall screws are essential construction materials used in hanging and securing drywall panels to wall studs or ceiling joists. These screws are typically made of hardened steel and have a sharp point for easy penetration into the drywall and wood framing. The most common size of drywall screws used in construction is 5/8 inches in length.

In addition to their size and thread design, drywall screws are also available in different materials and finishes to suit different applications. For example, zinc-plated screws are resistant to corrosion and are suitable for use in damp or humid environments, such as bathrooms or kitchens. Black phosphate-coated screws are often used for interior applications where appearance is not a concern.
