Frequently Asked Questions

What type of wood is this screw compatible with?

This screw is designed for fastening all types of wood decking, including cedar, redwood, and preservative-treated woods, making it a versatile choice for exterior deck construction and wood-to-wood fastening applications.

Why is Type 305 stainless steel used for this screw?

Type 305 stainless steel provides high-level corrosion resistance, making these screws well suited for exterior applications where exposure to moisture and the elements could cause standard steel fasteners to deteriorate over time.

Is predrilling required when installing these screws?

Predrilling is recommended near board ends to prevent splitting. The Type-17 point facilitates fast starts in most field conditions, but taking this precaution at board ends helps protect the integrity of your decking material.

What drive bit is needed, and is one included?

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