Unlike conventional screw studs used in many RV, marine and other OEM applications, this product will not snag clothing or deteriorate from exposure to sunlight, sand, or grit. What's even more amazing about SNAD fasteners is how they are secured to desire substrates. On the underside of each part is a pad of 3M, VHB acrylic conformation foam adhesive that enables the snap to adhere without drilling a hole. Installation is simple. Clean, peel, and stick! No tools!
