Product Overview
Made from Metric Grade A4 stainless steel, these screws come in a plain finish or NL-19 corrosion-resistant finish. NL-19 finishes are proprietary treatments that modify the surface of stainless steel fasteners, making them brighter, stronger and more corrosion-resistant than plain stainless steel. Grade A4 hex screws are more chemically resistant than Grade A2 stainless steel and are designed for chemical and marine environments to secure heavy-duty objects within or against other objects.
