FAQs
Where are SPAX fasteners available?
SPAX fasteners are available at most local home improvement retailers, industrial supply houses and online specialty woodworking outlets in the U.S. We are currently working to build a nationwide network of lumberyard and building materials suppliers.
Do your fasteners require pre-drilling for ICC and DrJ code-compliance?
No. Unlike traditional lags, SPAX PowerLags are IRC/IBC code compliant and DrJ code-compliant for deck ledger attachment multi-ply applications and do not require pre-drilling for full strength ratings, offering dramatically increased installation speed across your projects.
Can I use SPAX engineered fasteners in treated lumber?
Yes! Our 304 series stainless steel deck and construction screws, as well as our multi-purpose construction screws with HCR-X and PowerLags with high corrosion resistant (HCR) coatings are compatible with ACQ lumber. Reference the chart above for more information on our protective coatings.
