Frequently Asked Questions

Why is Type 316 stainless steel recommended for this application?

Type 316 stainless steel provides maximum corrosion protection, making these screws ideal for marine, seaside, and other high-exposure environments where PVC or composite decks are installed. It offers superior resistance compared to standard stainless grades, which is especially important in environments with salt air or moisture exposure.

Do I need to pre-drill before installing these screws?

Pre-drilling is not required in the field area, as the Type-17 point is designed for fast, self-starting installation. However, pre-drilling is recommended near board ends to prevent splitting the decking material.

What driver bit is needed, and is one included?

These screws use a T-15 6-lobe drive. One T-15 driver bit is included with the 70-piece pack. If you need a replacement bit, the compatible model is BIT15T-2-R2.

How does the Tan color match up with PVC and composite decking brands?

The Tan painted head is designed to blend with most major PVC and composite decking manufacturers. Simpson offers Trim-Head screws in 13 colors, allowing you to select the closest match to your specific decking product for a clean, low-profile appearance on the finished deck surface.
