Strong enough to pierce through several layers of material, it's ideal for jobs using marine canvas and upholstery fabric. Used in cloth-to-surface purposes, this screw stud attaches to a hard surface (like wood or fiberglass). Applications include boat covers, boat seats, gear bags, luggage, outdoor fabric, tents, and awnings. Lift-the-DOT setting tools make installing fasteners a breeze. For ultimate hold, Lift-the-DOT fasteners latch on three sides and release by raising the fourth side where the dot appears.
