Collated screws, also known as strip screws, are a popular fastening solution used in various industries. These screws are arranged in a strip, making it easier to load them into a tool and quickly fasten materials together. Collated screws come in different sizes, styles, and materials, making them suitable for various applications. However, choosing the right collated screw for your project can be overwhelming, especially if you are not familiar with the different options available. In this article, we will provide valuable tips to help you choose the right collated screws for your needs.
Tip #1: Consider the Material
The material of the screw is a vital consideration when choosing collated screws. Different materials offer varying levels of durability and resistance to corrosion, which can affect the screw's overall performance. Some common materials used for collated screws include stainless steel, zinc-plated steel, and aluminum. Here's a breakdown of each material:
Stainless Steel
Stainless steel collated screws are an excellent choice for applications exposed to harsh environments, extreme temperatures, or corrosive substances. Stainless steel is highly resistant to rust and corrosion, making it a durable option.
Zinc-Plated Steel
Zinc-plated steel collated screws are a popular choice because they are affordable and offer moderate corrosion resistance. However, they are not suitable for use in highly corrosive environments.
Aluminum
Aluminum collated screws are lightweight and offer excellent corrosion resistance, making them a great option for outdoor applications. However, aluminum screws can be more expensive than other materials.
Tip #2: Choose the Right Length and Diameter
The length and diameter of the collated screw also play a crucial role in determining its performance. Collated screws come in different lengths and diameters, making it essential to choose the right size for your project. The length of the screw should be longer than the material thickness to ensure proper penetration and engagement with the substrate. The diameter of the screw should also be appropriate for the material being fastened.
Tip #3: Look for the Right Type of Thread
The type of thread on the collated screw is another critical consideration when choosing the right screw for your project. There are two main types of thread: coarse thread and fine thread.
Coarse Thread
Coarse thread collated screws have a deeper and wider thread profile and are ideal for fastening materials with softwood and particleboard. Coarse thread screws have higher withdrawal resistance and are less likely to strip the material being fastened.
Fine Thread
Fine thread collated screws have a shallower and narrower thread profile and are best used for fastening materials with hardwood and metal. Fine thread screws have a lower withdrawal resistance and are more likely to strip the material being fastened compared to coarse thread screws.
Tip #4: Check the Strip Type
Collated screws come in different strip types, and it's essential to choose the right strip type for your project. The strip is what holds the collated screws together and feeds them into the tool. Here are the different strip types:
Wire Welded Strips
Wire welded strips are the most common type of collated screw strip. The screws are held together with a thin wire that is welded to the screw shank. The wire is flexible, allowing the screws to bend and conform to the tool's shape.
Paper Tape Strips
Paper tape strips are used for screws intended for drywall applications. The screws are held together with a paper tape that is compatible with automatic screw guns.
Plastic Strips
Plastic strips are used for screws intended for outdoor applications. The screws are held together with a plastic strip that is resistant to moisture and UV rays.
Tip #5: Consider the Head Style
The head style of the collated screw will affect its ability to sit flush with the material being fastened. Collated screws come in different head styles, including:
Flat Head
Flat head collated screws have a countersunk head that sits flush with the material being fastened. Flat head screws are used for applications where the screw's head must be concealed.
Pan Head
Pan head collated screws have a rounded top and are used for applications where the screw's head must be visible. Pan head screws are commonly used in the construction industry.
Round Head
Round head collated screws are similar to pan head screws but have a flatter top. Round head screws are suitable for furniture and cabinet applications.
Conclusion
Choosing the right collated screws can ensure a successful, long-lasting result for your project. Consider the material, length, diameter, thread type, strip type, and head style when choosing the right collated screws for your needs. If you are unsure about which collated screw to use, consult with a professional for expert advice.
