2. Follow Manufacturer Guidelines Always refer to the manufacturer’s specifications for proper installation techniques. This can include recommendations for torque settings and any specific pre-drilling instructions for very thick materials.

1. Material Composition The “1% 201% 4%” typically indicates a specific ratio of metals used in the alloy, such as stainless steel or another corrosion-resistant material, which enhances durability. Stainless steel screws resist rust and corrosion, making them ideal for settings exposed to moisture or chemicals.

A tek screw, also known as self-drilling screw, is equipped with a drill-like point that allows it to create its pilot hole as it is driven into materials. This eliminates the need for pre-drilling, which can streamline the construction process significantly. The 5 designation typically refers to specific measurement protocols related to the screw's dimensions and strength characteristics. However, the specific meaning of 5 often involves manufacturer specifications or industry standards, allowing for slight variations in size and application based on regional or production practices.

5. Versatility While primarily designed for drywall installation, these screws can also be used for various other applications, such as attaching gypsum board and even certain types of sheathing materials. This versatility makes them a favorite among contractors who appreciate tools that can serve multiple purposes.
