A194 2H Carbon Steel Xylan Coated Hex Nut ASME B18.2.4.1M
A194 2H carbon steel Xylan coated hex nut ASME B18.2.4.1M is a high-strength fastening component designed for industrial flange connections, pressure equipment, and heavy-duty bolting applications. The A194 2H carbon steel Xylan coated hex nut ASME B18.2.4.1M is manufactured from ASTM A194 Grade 2H carbon steel and finished with Xylan fluoropolymer coating, providing high mechanical strength, reduced friction, and enhanced corrosion protection.
The A194 2H carbon steel Xylan coated hex nut ASME B18.2.4.1M is widely used with ASTM A193 B7 stud bolts in petrochemical equipment, oil and gas systems, pressure vessels, pipelines, valves, and industrial machinery requiring reliable high-load fastening performance.
Product Overview
The A194 2H carbon steel Xylan coated hex nut ASME B18.2.4.1M is a heavy-duty hex nut designed for high-pressure and high-temperature bolting applications. ASTM A194 Grade 2H specifies the mechanical requirements for nuts used with pressure vessel and flange bolting systems.
The Xylan coating is a fluoropolymer-based protective finish that provides excellent lubricity, reduces thread friction, and improves resistance against corrosion and chemical exposure. Compared with untreated carbon steel nuts, the A194 2H carbon steel Xylan coated hex nut ASME B18.2.4.1M offers more consistent tightening performance and improved service reliability.
This product is commonly selected for critical flange assemblies where controlled preload and dependable connection strength are required.
