ASTM Standard Fasteners are high-quality mechanical fastening components manufactured in accordance with the American Society for Testing and Materials (ASTM) specifications. These standards ensure consistent material properties, mechanical performance, dimensional accuracy, and suitability for specific industrial applications, including structural engineering, petrochemical plants, power generation, oil & gas, automotive, and aerospace sectors.
ASTM fasteners are available in carbon steel, alloy steel, stainless steel, nickel alloys, and other exotic materials, and cover a wide range of fastener types including bolts, nuts, washers, studs, screws, and anchor bolts.
