Frequently Asked Questions

What type of wood decking are these screws compatible with?

These screws are suitable for fastening all types of wood decking, including cedar, redwood, and preservative-treated woods. The Type 305 stainless steel construction provides high-level corrosion resistance, making them well suited for exterior decking environments.

What drive type does the Simpson S10150DBB use, and is a bit included?

The S10150DBB uses a #2 square drive. A #2 square driver bit is included in each package. If a replacement bit is needed, the compatible replacement bit model is BIT2S-2-R2.

Is predrilling required when installing these screws?

Predrilling is recommended near board ends to prevent splitting. The Type-17 point is designed for fast starts in general installation, but taking care near the ends of boards helps protect the integrity of the decking material.

How do the coarse threads on this screw improve fastening performance?

The coarse threads run on approximately 2/3 of the shank, which draws the decking and other material tightly to the framing for a secure, stable hold. This thread design, combined with the bugle head, ensures flush countersinking and a clean finished surface on your deck.
