ASTM A194 Grade 4 Anchor Fasteners

The ASTM A194 Grade 4 Anchor Fastener assembly is engineered for heavy-duty, critical applications where both high strength and resistance to elevated temperatures are required. These fasteners typically consist of an anchor bolt (often ASTM A193 Grade B7) and matching ASTM A194 Grade 4 heavy hex nuts. Grade 4 nuts are manufactured from Alloy Steel, quenched and tempered, making them suitable for use with B7 bolting in demanding environments like power generation plants, refineries, and high-pressure piping systems. Zeron Fasteners specializes in providing complete, certified anchor fastener sets, ensuring dimensional accuracy and material integrity for secure and long-lasting structural anchorage.
