Jinjiang Tagong Hardware Forging Manufacturer Co. LTD
Pioneering the fastener industry with unwavering dedication since 1985, for a remarkable span of over 39 years.
Standard (GB / DIN / ISO / UNI / JIS / GOST / ANSI / ASTM ); And Tailor-made Non-standard crafted meticulously according to your unique designs.


Socket Nut (also known as threaded nut or hexagon socket nut) is a fastener with a hexagon drive hole, which usually needs to be installed and removed with a hexagon wrench (Allen Key) or a socket tool. This type of nut is widely used in mechanical assembly, automobiles, aerospace and other fields, especially in scenarios where space is limited or high torque fastening is required.
1. Structure and Features
Hexagon drive: with standard hexagonal holes (such as 1.5mm, 2mm, 2.5mm, etc.) on the top or side, suitable for hexagon wrench operation.
High torque load: compared with ordinary external hexagon nuts, it can withstand greater tightening force and reduce the risk of slipping.
Compact design: suitable for narrow spaces, avoiding the problem that external hexagon nuts cannot be used due to space limitations.
Various materials: carbon steel (grade 4.8, grade 8.8, grade 10.9), stainless steel (304, 316), brass, nylon, etc.
2. Common types
Type Features Typical applications
Standard Socket Nut Hexagonal hole at the top, general type Mechanical structure, equipment fixation
Low Profile Low height, save space Precision instruments, electronic equipment
Flanged type Flange at the bottom, increase contact area Prevent loosening, disperse pressure
Self-locking type (Nylon Insert) Built-in nylon ring, anti-loosening Vibration environment (automobile, aviation)
Anti-loosening serrated type Serrated at the bottom to enhance bite force High vibration equipment fixation
Welding type Can be welded on metal surface Steel structure, frame assembly
3. Application scenarios
Mechanical equipment: machine tools, automation equipment, robot joint fastening.
Automotive industry: high-strength connection of engines, gearboxes, and suspension systems.
Electronic equipment: PCB board fixation, shell assembly (applicable to low profile).
Aerospace: lightweight and high-strength fastening (titanium alloy or aviation aluminum).
Furniture and architecture: hidden fastening, such as high-end furniture and steel structure connection.
