Length: Long Tek screws are notably longer than standard Tek screws, typically ranging from 4 inches to 12 inches or more. The extended length allows them to penetrate thicker materials or reach deeper into the substrate, making them suitable for applications where a longer reach is necessary.
Thread Design: Long Tek screws have a thread design optimized for fastening into metal or wood substrates. The threads may be coarse or fine, depending on the specific application requirements. Coarse threads are typically used for wood substrates, while fine threads are more suitable for metal substrates.
Point Type: Long Tek screws often feature a self-drilling or self-tapping point at the tip, allowing for easy penetration into the material without the need for pre-drilled pilot holes. This feature saves time and labor during installation, especially in applications where drilling is challenging or impractical.
Head Types: Long Tek screws come in various head types, including hex head, pan head, flat head, and wafer head, among others. The choice of head type depends on the specific application and desired appearance. Hex head screws are commonly used for applications where a wrench or socket is required for installation, while pan head and flat head screws provide a flush finish.
Materials: Long Tek screws are typically made from hardened steel, stainless steel, or other materials with high strength and corrosion resistance. They may also be coated or plated with zinc, phosphate, or other finishes to enhance durability and prevent corrosion, especially in outdoor or corrosive environments.
Applications: Long Tek screws are used in a wide range of construction, roofing, HVAC, and metalworking applications where a secure and reliable fastening solution is required. Common applications include attaching metal roofing panels, securing structural components, and assembling metal or wood framing.
