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.

Moreover, these anchors are durable and resistant to environmental factors, making them suitable for both indoor and outdoor applications. For projects in humid areas, such as kitchens or bathrooms, metal anchors can withstand moisture better than many plastic alternatives.
