Sealtite ZXL #12 type 17 Woodbinder screws are designed to be used for oriented strand board (OSB). Coated screws feature a tough 2.5 mils of powder coating that will not chalk or fade due to the UV inhibitor in all colored coatings and the automated coloring process ensures a consistent color each batch. 5/16″ HWH with bonded sealing washer will completely cover existing hole, even if elongated by movement in the metal roof. The type 17 point will help clean the existing hole so that oversized threads can tap & generate maximum holding strength and the unique Strip-Loc threads are ideal for fastening metal panels to light density wood such as OSB. The loose EPDM gasket forms an excellent seal even when driven at an angle.
