Customized Double Hex Head Stepped Bolt
1.Double hexagonal head design, with two hexagonal structures on the upper and lower parts of the head, allows tools (such as wrenches or sockets) to be used to apply force separately at different installation stages (such as pre-tightening and final tightening) to avoid slipping or damage to the head.Suitable for scenarios where space is limited, such as when operation is required from the side or at different angles.
2.The step structure can accurately control the installation depth and ensure the alignment and clearance between components.
The step shares the shear force, reduces the stress concentration at the root of the thread, improves the vibration and impact resistance, and reduces the risk of fatigue fracture.
3. High-strength alloy steel (such as grade 8.8, grade 12.9) or stainless steel (A2/A4) are mostly used, and the surface treatment can be galvanized, Dacromet or phosphating to improve corrosion resistance.
Commonly used in precision machinery and instruments, automobiles and rail transportation, aerospace, heavy equipment and construction, electronics and electrical equipment and other industries.

How to choose the suitable hose clamps or throat hoops for your pipe?
1. Matching the outer diameter of the pipe
- The inner diameter of the throat clamp should be slightly smaller than the outer diameter of the pipe to ensure that there is no slippage after tightening (usually 5%~10% smaller).
- Example: If the outer diameter of the pipe is 50mm, the nominal inner diameter of the throat clamp should be about 47-48mm.
2. Pressure and medium requirements
- High pressure/high temperature environment: choose a wider American hose clamp (width ≥ 15mm) or a stainless steel German hose clamp.
- Corrosive media: German stainless steel hose clamps (A4 grade acid and alkali resistance) are preferred.
3. Industry standards
- Automotive industry: American hose clamps (SAE J1508) are more common and suitable for rubber pipes.
- Industrial pipelines: European projects mostly use German style (DIN standard), while North American projects tend to use American style.
