FastenMaster #0 x 6-in Black Ecoat Flat-Head Interior/Exterior Structural Wood Screws (12-Count)

HeadLOK is a heavy-duty wood screw that does it all with an internal drive and flat head. HeadLOK offers higher design shear than 3/8-in lag screws and no predrilling is needed. HeadLOK zips right in and is ideal for many wood-to-wood applications including deck, fences, SIPs, kitchen cabinets and more. The patented SpiderDrive eliminates cam-out and improves installation speed.
