Socket Clevis (fork-shaped connector) is a key connector in the fields of power transmission, communication cable installation and engineering fastening. It is forged from high-strength alloy steel. Its unique U-shaped fork design and threaded pin structure can efficiently connect insulators, cables, hardware and other components, and is suitable for high-voltage transmission line suspension, cable tension adjustment and equipment fixing scenarios. Socket Clevis produced by Handan Jinmai Fastener Manufacturing Co., Ltd. meets the requirements of international standards (such as ASME and ISO) with precise dimensional tolerances and reliable mechanical properties, providing safe and stable connection solutions for global customers.
1. High strength and corrosion resistance
Using hot-dip galvanizing or Dacromet surface treatment technology, the salt spray corrosion resistance is more than 1,000 hours, and it is suitable for harsh environments such as high temperature and humidity.
2. Modular and flexible design
The fork width and pin hole diameter support customized production, compatible with bolts and hardware accessories of different specifications, and reduce the complexity of system assembly.
3. Safety redundant structure
The double-ear symmetrical support design, combined with high-precision pin locking, can withstand dynamic load impact and avoid single-point failure risks.
4. Convenient maintenance throughout the life cycle
The batch number and load level are laser engraved on the surface for easy inspection, traceability and replacement.
1. Raw material selection
Select low-alloy high-strength steel billets such as Q345B and 35CrMo, and put them into production after the composition is tested by a spectrometer.
2. Precision forging
Through die forging with a 2,000-ton hydraulic press, internal pore defects are eliminated, and the density and fatigue resistance of the product are improved.
3. CNC machining
Five-axis linkage CNC machine tools are used to process key contact surfaces, and the aperture tolerance is controlled within ±0.05mm to ensure assembly consistency.
4. Surface treatment and quality inspection
After fully automatic shot blasting and rust removal, hot-dip galvanizing (average coating ≥85μm) or environmentally friendly Dacromet coating process is performed, and double verification is passed by magnetic particle inspection and tensile test (destructive load ≥2 times rated value).
Handan Jinmai Socket Clevis series covers nominal loads from 3 tons to 50 tons, with compatible pin diameters from 12mm to 80mm and fork widths from 30mm to 200mm. The main material has a tensile strength of ≥800MPa, a yield strength of ≥640MPa, and an operating temperature range of -40℃ to +150℃.
