Performance Advantages of Tianlong Dual - Material Hardlock Nuts

1. Dual - Material Hardlock Nuts Feature Outstanding Anti - Loosening Performance

Tianlong Dual - Material Hardlock Nuts consist of two upper and lower self - tightening nuts. The upper nut has a bevel, and the lower nut is provided with a groove, which is an exquisite structural design. When locked, the two bite together to form a conical structure, and can maintain excellent anti - loosening effect under high - speed operation and strong vibration working conditions.

2. Dual - Material Hardlock Nuts Have Diverse Materials to Meet Various Needs

S45C (corresponding to the national standard 45# steel): It is a medium - carbon steel with good performance, having a certain degree of toughness, plasticity and relatively high strength, and good machinability.

40Cr: It is an alloy structural steel. After treatment, its strength and hardenability are better. The tensile strength can reach 980Mpa, the yield strength is 785Mpa, and the elongation is > 9%.

3. Dual - Material Hardlock Nuts Have a Wide Range of Specifications

The thread sizes of Tianlong Dual - Material Hardlock Nuts cover M8 - M48, which can be adapted to many different devices and simplify the procurement process.

4. Multiple Surface Treatments of Hardlock Nuts for Adaptable Environments

The black surface treatment can improve wear resistance and rust resistance, and make the appearance of the nut more beautiful and regular. The galvanized treatment enhances the corrosion resistance of the nut.

5. Origin Advantage and High Market Recognition

In the market, a large number of these nuts are used in China's high - speed railways (about 50 million pieces, accounting for 42% of the global market). After practical verification, the performance of Dual - Material Hardlock Nuts has been internationally recognized. Besides high - speed railways, they can also be used in coal mining, tunnel excavation, road reinforcement, and geotechnical engineering fields.
