Coated Structural Fasteners

Intended for wood-to-wood connections in exterior structural applications with treated lumber components, Spax PowerLags T-Star Washer Head wood lag screws with HCR (high corrosion resistance) coating have a low-profile, large-diameter wafer head that the manufacturer claims provides additional surface area under the head for superior pull-down force. They require no predrilling and are available in 1/4-inch, 5/16-inch, and 3/8-inch diameters in lengths up to 10 inches. Pricing varies. spax.us
