Case Study

Driving A Dealer’s Profitability

We analyzed our dealer partner’s fastener category and utilized our comprehensive product offering to help them minimize the number of brands they carry. The final result: the dealer consolidated the category, while still maintaining a complete offering. The consolidation allowed the dealer to take back six feet of shelf space.

What makes SPAX engineered fasteners different than other fastener products?

Strength and job site efficiency innovations such as our patented 4-CUT point, serrated threads, HCR-X™ coating for advanced corrosion resistance, ZERO pre-drilling and comprehensive product testing means SPAX Engineered Fasteners are the most advanced fastener product on the market, providing the power to keep your projects connected stronger for longer.

Can SPAX engineered fasteners be used 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.

Do SPAX engineered 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.
