ASTM AISI ANSI SUS SS 304 316 316L A2 A4 70 80 Hanger Metal Bolt With Nut Flange Nut Hot Sale

This hot-selling series of stainless steel hanger bolts offers a complete fastening solution, packaged with matching nuts or flange nuts for convenience and guaranteed compatibility. Available in the most popular stainless steel grades—SS304, SS316, and SS316L—these bolts meet a wide array of international standards including ASTM, AISI, ANSI, and SUS, ensuring global acceptance and quality assurance. The materials are further classified by strength, with options for A2-70 (304 stainless, 700 MPa tensile), A4-70 (316 stainless, 700 MPa), and A4-80 (316 stainless, 800 MPa), providing a range of strength levels to suit different load requirements. The bolts feature a standard hanger design with a wood thread on one end and a machine thread on the other. The included nuts—either standard hex nuts or serrated flange nuts—are manufactured from matching stainless steel grades, ensuring uniform corrosion resistance and galvanic compatibility throughout the assembled joint.

This comprehensive fastener set is a versatile solution for a vast range of industries where corrosion resistance is a primary concern. The combination of bolt and nut makes it ideal for:

• Marine and Offshore Applications: Boat building, dock hardware, and offshore platform fittings where exposure to saltwater is constant. SS316/316L (A4) is the preferred choice here.
• Food and Beverage Processing: Equipment assembly, conveyor systems, and sanitary fixtures where hygiene and resistance to cleaning chemicals are critical.
• Architectural and Construction: Outdoor railings, signage, structural glazing supports, and facade attachments where long-term weather resistance and aesthetic appearance are required.
• Chemical and Pharmaceutical Plants: For equipment and piping supports in corrosive environments.
  The inclusion of a matching nut simplifies procurement and ensures a perfect thread fit and material match, preventing issues like galling or galvanic corrosion that can occur with mismatched components.

The core advantage is the complete, matched system, providing a bolt and nut that are metallurgically compatible, eliminating the risk of galvanic corrosion and ensuring consistent strength and longevity. The availability of three premium stainless grades (304, 316, 316L) and two strength levels (70 and 80) allows for precise material selection based on the specific corrosivity and mechanical demands of the application. The option of a flange nut provides an integrated washer, distributing clamping loads evenly and offering enhanced resistance to loosening due to vibration. As a hot-selling line, these products represent a proven, reliable, and cost-effective solution for a vast number of applications, with the convenience of ready-to-use kits simplifying inventory management for distributors and end-users alike.
