NEXT GENERATION LAG SCREW - Power-Thread structural screws are made with case hardened steel for strength, and a self-drilling thread for fast installation, resulting in a stronger and easier- to-use fastener.
NO PRE-DRILLING - Cork screw tip and blade cutting threads provide easy piercing and fast driving while reducing strain on the material.
REAMER THREAD - The reamer thread creates a larger passage for the unthreaded shank to easily draw materials together, and reduces tension on the screw head.
SERRATED UNDERHEAD - Serrations on the underside of the screw head embed into the wood to countersink the head and help prevent loosening.
DOME HEAD DESIGN - Enhances the structural capability of the screw, and provides a smooth surface.
CORROSION RESISTANT COATING - RoHS compliant coating is approved for use with alkaline copper quaternary (ACQ) pressure treated lumber.
PRECISION POWER-THREAD TORX® TYPE / STAR RECESS - When used with Power-Thread Torx® Type / Star insert bits, the tight fit holds the screw so it can be installed with one hand without the screw falling off. Screws can also be installed with standard Torx® Type / Star bits.
Note: Torx® is a Registered Trademark of Acument Intellectual Properties.
