Frequently Asked Questions

What type of wood decking materials are these screws compatible with?

These screws are designed for fastening all types of wood decking, including cedar, redwood, and preservative-treated woods, making them a versatile choice for a wide range of exterior deck construction projects.

Why is a Type-17 point important on a deck screw?

The Type-17 point is specifically engineered for fast starts, allowing the screw to self-pierce into wood quickly and efficiently, reducing the effort required during installation and helping to prevent surface splintering on entry.

Do these screws require predrilling?

Predrilling is recommended near board ends to prevent splitting. While the Type-17 point and coarse thread design support efficient installation in field applications, taking care near the edges and ends of boards helps maintain the integrity of the decking material.

What corrosion resistance does Type 305 stainless steel provide?

Type 305 stainless steel provides high-level corrosion resistance, making these screws well suited for exterior decking applications where exposure to moisture and the elements is a concern. This material is particularly appropriate for use with cedar, redwood, and preservative-treated wood decking.
