Frequently asked questions about countersunk wood screws

Can I use these screws outdoors or in marine environments?

These screws are manufactured in A2 stainless steel offering a high level of corrosion-resistant, making these screws suitable for both internal and external projects. For areas near salt water and marine environments, A4 stainless steel is recommended for longer lasting results.

What size pilot hole should I drill?

For hardwoods, a pilot hole slightly smaller than the screw diameter is recommended. For softwoods, the pilot hole can be narrower or sometimes skipped.

Are A2 stainless slotted screws magnetic?

No, A2 stainless steel screws are typically non-magnetic or only slightly magnetic after cold working.

Can you use stainless wood screws in outdoor, treated, or tannin-rich woods (like cedar/redwood)?

Yes, stainless steel is recommended in treated lumber and tannin-rich woods to prevent staining and corrosion. For coastal areas, A4 stainless steel is the best which offers as much higher level of corrosion resistance. 

How do stainless fasteners compare in strength to other steels?

A2 stainless steel offers high corrosion resistance needed for external use, but it is generally not as hard or high tensile as carbon steel. Stainless steel screws are still more than adequate for most wood fixing jobs.
