The Ultimate Screw: Ultra Tec 1/8-Inch Hex Head

The Ultra-Tec 1/8-inch hex head screw is a fastener made from type 316 stainless steel and used for 1/8 and 3/16 cable. It is designed for metal-to-metal fastening and is suitable for use in HVAC, duct work, and steel stud framing. The screw is typically available in packs of varying quantities, such as 170 or 280, and can be purchased from hardware stores or online retailers.

Self-tapping hex head cap screw

The Ultra-lok Self Tapping Hex Head Cap Screw, for example, features an oversized design that allows it to cut its own threads. This screw is made from heat-treated material that provides outer case hardness, enabling it to serve as a tap-like cutter. It meets or exceeds the mechanical properties of the tensile strength of a grade 8 fastener and is temperature resistant.

In addition to the standard self-tapping hex head cap screws, there are also self-drilling variants available. These screws are designed with a drilling tail that allows them to create their own hole in the material, eliminating the need for a pilot hole. Self-drilling screws are commonly used in metal-to-metal applications, HVAC, duct work, and steel stud framing. They provide a secure and efficient fastening solution for a range of projects.

Socket-head screws

One example of a socket-head screw is the Ultra-Tec 1/4-28 x 1/2" Socket-Head Screw, which is made from Type 316 stainless steel and is used for 1/8" and 3/16" cable. This particular screw is available from Wagner and is sold in packs of 1,000.

Another option is the Ultra-lok Self Tapping Hex Head Cap Screw, which is a Grade 8 quality fastener with a 1/4-20 x 1" size. This screw is designed to cut its own threads, eliminating the need for tapping. The Ultra-lok screw is temperature-resistant and meets or exceeds the mechanical properties of a grade 8 fastener. However, it is currently unavailable on Amazon.

For projects requiring a large number of screws, the Teks brand offers Hex Head Self-Drilling Screws in packs of 170 or 280. These screws are designed for metal-to-metal fastening and are suitable for use in HVAC, duct work, and steel stud framing. The Teks screws feature an external hex flange head and are available in a range of sizes, including #8 x 1" and #8 x 1/2".

When choosing socket-head screws, it is important to consider the material, size, and intended application to ensure that the screws are suitable for the project. Stainless steel screws, such as those from Ultra-Tec and Teks, are strong and durable, making them ideal for heavy-duty applications. Nylon screws, like the Nylo-Tec Bi-Hex Head Self-Drill Screws, offer corrosion resistance and are often used in electrical applications.

Metal to metal fastening

Metal-to-Metal Fastening with Ultra-Tec 1/8 Inch Hex Head Screws

The Teks #8 1-inch External Hex Flange Hex-Head Self-Drilling Screws are ideal for metal-to-metal fastening. These screws are designed for use in HVAC, duct work, and steel stud framing metal fastening. The self-tapping, self-drilling feature of the screws eliminates the need for pre-drilling, making the installation process more efficient.

Features and Benefits:

• Self-Tapping and Self-Drilling: The Teks Hex Head Screws are designed to tap their own threads and drill their own hole, eliminating the need for pre-drilling. This feature simplifies the installation process and reduces the time and effort required.
• Metal-to-Metal Fastening: These screws are specifically engineered for fastening two metal surfaces together. They provide a strong and secure hold, making them ideal for applications such as HVAC, duct work, and steel stud framing.
• External Hex Flange Head: The external hex flange head design provides a larger bearing surface, distributing the clamping force over a wider area. This feature helps to reduce the risk of deformation or damage to the fastened materials.
• Corrosion Resistance: Made from high-quality materials, these screws offer corrosion resistance, ensuring their long-term durability and performance in various environments.

Installation Guide:

To ensure proper installation and maximum holding power, follow these steps:

• Surface Preparation: Clean and prepare the metal surfaces to be joined. Ensure they are free from dirt, grease, or debris.
• Drill Pilot Hole: Although the screws are self-drilling, it is recommended to drill a pilot hole, especially when working with thicker or harder metals. This helps guide the screw and reduce the risk of stripping or breaking.
• Drive the Screw: Using a suitable hex key or driver, insert the screw into the pilot hole and drive it until the head is flush with the surface. Ensure that you do not overtighten, as this can strip the threads or damage the fastened materials.
• Torque Specification: Refer to the manufacturer's instructions for the recommended torque settings. Tightening the screws to the specified torque ensures optimal holding power and prevents damage to the screws or fastened materials.
• Inspection: After installation, inspect the screws and fastened materials for any signs of damage or deformation. Ensure that the screws are securely in place and that the joint is stable and strong.

By following these instructions and utilizing the Teks #8 1-inch External Hex Flange Hex-Head Self-Drilling Screws, you can confidently fasten metal-to-metal connections with strength and durability.

Bi-hex head self-drill screw

The self-drilling feature of these screws is another key advantage. Self-drilling screws, also known as self-tapping screws, are designed with a pointed tip that acts like a drill bit. This tip cuts into the material, eliminating the need for pre-drilling and significantly streamlining the installation process. This is especially beneficial in construction and manufacturing, where efficiency and speed are crucial.

One notable example of bi-hex head self-drill screws is the Nylo-Tec line, which offers these screws in both 1-inch and 2-inch lengths. The screws are made of nylon and feature a white bi-hex head. They are sold in packs of 100, providing a substantial quantity for various projects. These screws are suitable for a range of applications and demonstrate the versatility of this type of fastener.

Another noteworthy option is the Bi-Flex® Hex Washer Head screws from DEWALT. These screws are bi-metal, combining the corrosion resistance of 300 series stainless steel and the efficiency of drill screws. This dual-material construction makes them ideal for connections involving steel, aluminium, and wood. The Bi-Flex screws are designed for structural applications, providing high strength, ductility, and reliability. They are also immune to hydrogen-assisted stress corrosion cracking (HASCC), ensuring long-term durability.

In summary, bi-hex head self-drill screws offer a combination of convenience and performance that makes them a popular choice for professionals and DIY enthusiasts alike. With their unique head design and self-drilling capability, these screws streamline the fastening process while providing secure and reliable connections in a variety of materials. Whether it's the Nylo-Tec or Bi-Flex options, or other similar products, these screws are a versatile and efficient solution for a wide range of applications.

Stainless steel
