A194 2HM Heavy Hex Nut Manufacturer In China

Ningbo Teng Qi Fasteners Co., Ltd is a leading A194 grade 2HM heavy hex nuts manufacturer in China. A194 2HM nuts are heavy hex nuts designed for use in high-pressure and high-temperature applications, typically in conjunction with A193 B7 bolts. These nuts are commonly used in industrial settings, especially in oil and gas, petrochemical, and power generation industries. The “A194” denotes the specification for high-strength industrial nuts, and “2HM” specifically refers to the heavy hex pattern and material grade. These nuts are often heat-treated to provide the necessary strength and durability for demanding environments.

Our advanced cold heading and hot forging processes enable us to produce a comprehensive size range, spanning from 1/4″ to 4″.

Crafted from medium carbon steel C45, control A194 2HM nuts hardness range of 159-237. We meticulously control the tempering process, ensuring temperatures exceed 1150 ℉ to achieve optimal mechanical properties.

To enhance performance, we offer various surface treatments, including black oxide for a refined appearance, galvanization for corrosion resistance, hot-dip galvanization for extended durability, and zinc flake coatings for prolonged protection.

At Ningbo Teng Qi Fasteners, our commitment to precision, quality, and customer satisfaction is embedded in every A194 Grade 2HM heavy hex nut we produce. With 20 years of industry experience, we stand as a reliable partner for your fastener needs.

Application of A194 2HM Heavy Hex Nuts:

A194 2HM nuts are commonly used in heavy-duty applications where robust fastening is crucial. Here’s a simple introduction to their application:

A194 2HM nuts, known for their durability and strength, are extensively utilized in heavy-duty applications. Whether in construction, machinery, or infrastructure projects, these nuts play a critical role in securely fastening components together. Their medium carbon steel construction (C45) and controlled tempering process result in a hardness range of 159-237, making them ideal for environments where toughness and resilience are paramount. From large-scale structures to machinery assembly, A194 2HM nuts contribute to reliable and steadfast connections in various industries.

These nuts are often employed in flange connections, where they help secure the flange to the pipe or equipment by applying the necessary clamping force. By using A194 heavy hex nuts in combination with A193 B7 studs or bolts, engineers can ensure reliable and robust connections that can withstand high stress and temperature variations.
