ASTM A194 2H Heavy Hex Nuts
ASTM A194 2H heavy hex nuts from Ningbo S&D Metalwork Co., Ltd are carbon and alloy steel fasteners designed for high-pressure, high-temperature applications, including flange connections in piping systems. The 2H grade meets the standard for heat-treated nuts with a minimum hardness of 223 HB, while the 2HM variant adds corrosion resistance through additional heat treatment. Sizes range from 1/4 to 4 inches, with finishes available in plain, black oxide, zinc plated (ZP), zinc yellow (ZY), and hot-dip galvanised (HDG) to suit different environmental conditions.
The nuts are manufactured from carbon steel, alloy steel, or stainless steel, with material selection tailored to the mechanical and chemical demands of the application. Carbon steel variants are standard for general industrial use, while alloy steel grades such as 2HM provide enhanced strength for critical joints. Typical industry tolerances for heavy hex nuts include a thread fit of 6g for external threads, and the nuts are often paired with ASTM A193 bolts for compatible strength and performance in bolted assemblies.
These nuts are widely used in oil and gas, petrochemical, and power generation sectors where structural integrity under thermal cycling is essential. Buyers typically source them in bulk with packaging of 25 kg per box and 36 boxes per pallet for efficient handling and logistics. The supplier accepts OEM specifications and custom branding, making them suitable for integrators and distributors requiring tailored solutions.

Sourcing ASTM A194 2H Heavy Hex Nuts from Ningbo S&D Metalwork Co., Ltd - China Import Guide
Before ordering, verify the exact grade and material composition to ensure compatibility with your application’s temperature and pressure requirements. ASTM A194 2H nuts are carbon or alloy steel, while 2HM adds corrosion resistance, so confirm which variant meets your environmental conditions. Additionally, check that the thread class (e.g., 6g) matches your bolts to avoid assembly issues.
Confirm logistics details such as lead time, which can vary based on size, finish, and order volume. Standard Incoterms for bulk fastener shipments from China often include FOB Ningbo or CIF to the destination port, with payment terms typically set as TT or LC. Request the supplier’s preferred terms and any volume discounts for palletised orders.
Inspect a sample batch for hardness, dimensional accuracy, and finish quality before full production. For critical applications, require a third-party inspection report or material test certificate (MTC) to EN 10204 3.1 or 3.2 standards. Ensure packaging is intact and labeled with grade, size, and batch number for traceability during transit and storage.
