IMPORTANT INFORMATION REGARDING STAINLESS STEEL TAPCONS
The 410-grade stainless steel will stick to the magnet even though it is stainless steel of a lower grade.The 410-grade stainless steel resists corrosion in dry atmospheres, freshwater, acids, mild alkalies, food, hot gasses and steam. Tapcons are coated with Climaseal®. This coating, when applied on top of 410 stainless steel, gives these concrete screws superior rust resistance. This coating is called a thermosetting polyester coating and is a result of a three-step process. First, the concrete screws are cleaned and pre-treated and a zinc overcoat is mechanically applied. Second, a first coating of Climaseal® is applied by dipping each screw into the liquid then spinning each screw. This provides consistent coverage and quality. During the third and final step, the screws are dried in a furnace before the second coat of Climaseal® is applied.
