Coosa Board, with its foam composition, has different screw retention properties compared to plywood. It is important to note that Coosa Board has less screw retention than plywood. This means that screws may not hold as securely in Coosa Board as they would in plywood.
To ensure proper and secure fastening of Coosa Board, it is recommended to use special fasteners such as stainless steel t-nuts or to through-bolt the board. These fasteners are designed to provide a stronger and more reliable connection to the Coosa Board.
Thru-bolting involves using bolts that go all the way through the Coosa Board and are secured with nuts on the other side. This method distributes the load more evenly and can provide a stronger connection compared to screws alone.
Stainless steel t-nuts are another option for securing Coosa Board. These t-nuts have teeth or prongs that dig into the wood when installed, creating a more secure grip. This can help prevent the screws from loosening or pulling out over time.
It is important to select the appropriate size and type of fastener for the specific application and load requirements. Consulting the manufacturer’s recommendations or seeking advice from a knowledgeable professional can help ensure the right fasteners are used.
In my personal experience, I have used Coosa Board in various marine applications where screw retention was a concern. I have found that using stainless steel t-nuts or through-bolting has provided a reliable and secure connection. However, it is always important to thoroughly test and evaluate the fastening method to ensure it meets the specific needs and requirements of the project.
To summarize, Coosa Board has less screw retention than plywood due to its foam composition. To ensure a secure and reliable connection, it is recommended to use special fasteners such as stainless steel t-nuts or to through-bolt the board. Proper selection and installation of these fasteners are crucial for ensuring the longevity and stability of the Coosa Board installation.
