SPAX® products have been my go-to screws and lags in my shop for years. From construction projects to furniture building, they have the best products. The screws and lags are well designed and are far superior to other like brands. Even though the hardware is rarely ever seen in the final piece, I know that it will last a lifetime, because I choose to use SPAX®!

Do you Know Where Your Fasteners Were Made?
While most of our competitors ship screws in from overseas, we continuously innovate and make our fasteners from the heart of America to reimagine what structural connections should be. That means our products are ready to deliver and stock right now from our Ohio HQ to our neighbors across the U.S.
SPAX

90%

Optimal rigidity, malleability, and material strength
Proprietary heat treatment process optimizes each fasteners shear strength without breakage.
SPAX is Independently Tested and Approved
DrJ Engineering TER reports use specialized testing and industry-approved evaluations to certify that products meet specific performance requirements of the appropriate sections of the appropriate building code. We follow ICC AC257 acceptance criteria for all exterior coated screws.
Residential
Building Code
Our Double Barrier Coating
Our HCR® (High Corrosion Resistance) double-barrier coatings offer superior protection with a double barrier. First plated with a zinc base coat and finished with a durable top coat, they’re engineered to hold up to the harshest conditions. Tested and recognized for use in ground contact pressure treated lumber for exterior, freshwater general construction applications (e.g., AWPA UC1-UC4A, UCFA).
DID YOU KNOW?
Some competitors don’t actually test their coatings. They rely on data from their paint company before it makes it onto their screws.
Tested Beyond the Norm
We test and inspect beyond all standards to deliver exceptional structural support—from head to point. Push past what’s expected with time-tested confidence in every connection.
