Buying Guide
Choosing the right screws for your trailer decking project can seem overwhelming, but it doesn’t have to be. Here are a few key factors to consider to help you make the best decision:
- Material: Consider the type of decking material you’re using. Different materials require different types of screws. For example, composite decking may require screws with a different thread pattern than wood decking.
- Corrosion Resistance: If your trailer will be exposed to moisture or harsh weather conditions, choose screws with excellent corrosion resistance. Stainless steel or coated screws are good options.
- Head Type: The head type can affect the appearance and functionality of your deck. Trim head screws provide a clean, finished look, while flat head screws offer good holding power.
- Size: Choose the appropriate screw length for the thickness of your decking material. The screw should penetrate deep enough into the frame to provide a secure connection.
- Drive Type: Consider the drive type of the screw. Star drive (Torx) and square drive screws are less likely to strip than Phillips head screws.
- Quantity: Estimate the number of screws you’ll need for your project and buy accordingly. It’s always a good idea to have a few extra on hand.
