CTX #15 Construction Lag Screw

Bronze Coated #15 x 2.5" Screw

The Big Timber CTX #15 construction lag screws are heat-treated hardened steel for high tensile and high shear strength with triple layer ACQ compatible bronze coating.

The deep six-lobe star drive recess reduces cam-out end load while the built-in washer head offers increased pull through strength.
