To accurately size screws for joist hangers, it’s crucial to take into account the thickness of the employed materials and the specific joist hanger being installed. Ensuring a secure connection, recommended screw lengths dictated by manufacturers should extend beyond the joist to encompass the ledger board or beam.
Although the acceptable screw length may fluctuate according to joist hanger and material, following manufacturer guidelines is vital for seamless integration.
What Type of Screws Are Recommended for Joist Hangers in Commercial Settings?
One type of screw that is commonly recommended is the flanged bugle head screw. These screws feature a distinctive flanged head that provides a secure grip on the joist hanger, reducing the risk of rotation or slipping.
In addition to their design, flanged bugle head screws are also made from high-strength materials such as grade 2 stainless steel or aluminum alloys. This ensures that they can withstand the heavy loads and stresses associated with commercial buildings, where the weight of the structure, furniture, and equipment can be considerable.
Another benefit of flanged bugle head screws is their ability to be easily driven into dense or hardwood joists. This is because their bugle head shape allows them to be sunk into the material, providing a flush surface and preventing the head from rising above the surface. This can be especially important in commercial settings where aesthetics are a concern.
It’s also worth noting that flanged bugle head screws are designed to be easily accessible for maintenance and repair purposes. This means that if a screw needs to be replaced or tightened, it can be done quickly and easily without having to remove surrounding materials. flanged bugle head screws are a reliable and practical choice for joist hangers in commercial settings, offering a combination of strength, security, and ease of use.
Can You Use Screws Other than Framing Type Nails for Joist Hangers?
However, what if you want to try something different? Can you use screws instead? The answer is yes, but with some caution.
Screws can be a valuable alternative to framing type nails for joist hangers, but you need to choose the right type of screw. Look for screws specifically designed for heavy-duty applications, such as deck screws or lag screws. These screws are better suited for withstanding the weight and stress of a joist hanger. When selecting a screw, make sure it’s long enough to go through the hanger and into the beam without stripping the wood. A general rule of thumb is to use a screw that’s 1-2 inches longer than the beam’s thickness.
- Advantages of using screws:
- Screws provide a more secure hold than nails, especially in high-stress areas.
- They can be easier to install, especially in tight spaces.
- Screws can provide a neater finish than nails.
- Disadvantages to consider:
- Screws can be more difficult to remove than nails.
- They can be more expensive than nails.
- They may require pre-drilling a hole to avoid splitting the wood.
What is the Importance of Selecting Joist Hangers with Corrosion-resistant Finishes?
Joist hangers are essential for connecting joist to beams, and they play a critical role in holding the structure together. However, not all joist hangers are created equal. Some joist hangers come with corrosion-resistant finishes, which are essential for building structures that can withstand the elements.
Corrosion-resistant joist hangers are designed to resist rust and corrosion, which can weaken the structure over time. When joist hangers corrode, they can cause the joist to shift or pull away from the beam, leading to structural damage and potentially even collapse. By choosing joist hangers with corrosion-resistant finishes, you can ensure that your structure remains strong and secure.
In coastal or industrial areas where salt and chemicals are present in the air, corrosion-resistant joist hangers are a must. These areas pose a higher risk of corrosion due to the environment, making it essential to choose joist hangers that can withstand these conditions.
Furthermore, corrosion-resistant joist hangers are important for high-rise or sensitive structures. Buildings that are sensitive to movement, such as hospitals or schools, require a stable and secure structure to ensure the safety of occupants. Corrosion-resistant joist hangers provide peace of mind knowing that the structure is designed to withstand the elements and resist corrosion.
When selecting joist hangers, it’s essential to consider the environment in which the structure will be built. If the building will be exposed to moisture, salt, or chemicals, choose joist hangers with corrosion-resistant finishes. Additionally, always follow manufacturer guidelines for installation and maintenance to ensure the longevity of the joist hangers and the structure as a whole.
