SPAX® Delivers the Highest Structural Values in the Industry
Building a Log Home
Log Home building has evolved through years of construction changes. There are many different types of fasteners used for the installation of log walls. These types of fastening systems included spikes, lag screws, threaded rods and specialty spring systems.
SPAX® FASTENERS FOR LOG HOME CONSTRUCTION
SPAX® manufactures Log and Timber PowerLags® specifically for the log home construction. This product carries many features to assist in the building of these unique style homes. The patented serrated threading allows the Log and Timber PowerLags® to require no pre-drilling. This feature speeds the installation process to reduce time and labor costs. SPAX® offers the product in 2 distinct head styles that both have a T-STAR internal drive system. This drive system has 6 points of bit engagement to eliminate drive stripping and provides product confidence. The coating system is an epoxy coating that offers corrosion resistance from moisture during the construction phase. The unique black color also provides quick identification to spacing requirements for installation. SPAX® heat treats these high quality steel to match structural connections needed for strength to the structural wall. SPAX® offers these products in the largest portfolio of lengths available for the majority of log profiles in the market today.

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.
