2h Nut

2H Nut, also known as A194 2H grade nut, is a high-strength fastener. Made from carbon steel or alloy steel, it features high strength and good toughness. With various surface treatments like zinc-plating and nickel-plating for enhanced corrosion resistance, it comes in a wide range of thread sizes from M6 to M48, meeting diverse application needs. Commonly used with bolts and screws, it plays a vital role in industries such as machinery, construction, and automotive for secure connections.

High-strength Material Ensures Durability
2h Nut is crafted from high-strength alloy steel, undergoing a special heat treatment process to achieve a hardness of HRC 40-45, far surpassing the HRC 25-30 of ordinary nuts. This high hardness not only makes 2h Nut resistant to deformation during long-term use but also allows it to withstand greater mechanical stress, extending its service life. Under the same load conditions, the service life of 2h Nut is approximately 60% longer than that of ordinary nuts.

Precision Waterproof Design Enhances Corrosion Resistance
The surface of 2h Nut undergoes multiple layers of electroplating, including a zinc-nickel alloy coating and a sealing layer, forming a dual protective barrier. This design grants it an IP68 waterproof rating, capable of enduring immersion in water up to 1 meter deep for 30 days without rusting. In contrast, ordinary nuts only receive a single layer of zinc plating, resulting in poorer waterproof performance and susceptibility to corrosion in humid environments. The corrosion resistance of 2h Nut makes it particularly suitable for harsh environments such as outdoors and marine settings.

High-temperature Resistance for Extreme Conditions
2h Nut employs high-temperature resistant alloy materials, maintaining stable performance within a temperature range of -50°C to 300°C. Its internal structure has been optimized to effectively prevent thread loosening even in high-temperature environments.

High-pressure Resistance Design Ensures Safety
The threads of 2h Nut undergo precision machining, adopting a unique locking structure design capable of withstanding pressures up to 1000 MPa. This design ensures a stable connection in high-pressure environments, avoiding safety hazards due to loosening. The tensile strength of 2h Nut in high-pressure environments is approximately 40% higher than that of ordinary nuts, making it especially suitable for high-load scenarios such as heavy machinery and bridges.

Lightweight Design Enhances Usability
Despite its high strength and durability, 2h Nut boasts a weight reduction of approximately 20% compared to traditional nuts. This improvement is attributed to material optimization and structural design, making it easier to handle and install while ensuring performance, particularly suitable for scenarios requiring frequent disassembly.
