Product Description

Nylock Nuts

The coupling nut (also known as the connecting nut or extension nut) is a long hexagonal nut, which is mainly used to connect two rods with external threads (such as bolts, screws, pipes, etc.) to extend, dock or adjust the length. It is widely used in mechanical transmission, building structure, automation equipment and other fields.

1. Structure and characteristics
Long hexagonal shape: longer than ordinary nuts, with full-through threads inside.
Symmetrical at both ends: usually both ends have the same specification of threads (such as M8, M10).
High load capacity: increase the connection strength by increasing the bite length to avoid loosening.
Various materials: carbon steel (grade 4.8/grade 8.8), stainless steel (304/316), brass, etc.
2. Main types
Type Features Typical applications
Standard coupling nut Hexagonal shape, general purpose Mechanical transmission, screw connection
Flange coupling nut With flange surface, enhanced anti-loosening Vibration environment (such as conveying equipment)
Knurled coupling nut Surface knurling, easy manual adjustment Optical instruments, precision equipment fine-tuning
Stainless steel coupling nut Corrosion-resistant, suitable for humid/chemical environments Food machinery, marine equipment
3. Core functions
Extend threaded rods: such as connecting two bolts or screws to form a longer structure.
Adjust the installation distance: By screwing the coupling nut, the total length can be accurately controlle.
Transmit torque: Used as a threaded coupling in the transmission system (such as a ball screw).
Sealed pipe connection: Some models are used for high-pressure pipeline thread connection (sealant is required).
