NOVA™ Structural Lag Screw - Star Drive

NOVA™ Structural Lag Screws are the superior lag screw for any of your projects.

With a strong thread that ensures maximum withdrawal strength and a Fast Start Tip that easily grips and cuts its way through the wood, you will feel the power and quality of the NOVA.

The Self-Tapping Thread cuts effectively through materials such as wood, plastic and sheet metal.

The patented Twin Blade Knurls1 ensure minimum friction on the shank and the Locking Wedges under the head countersink perfectly with maximum wood contact.
