Product Description
Specifications
Hex bolt1.use for Wind tower
2.Size: M12-M56
3.Finish:plain, zinc plated, hot dip galvanized, dacroment
1)Ttighter quality control system.
2) NDT: fluorescent magnetic particle inspection + eddy current separation
3) Metallurgical analysis: the organization is more complex due to the large size of the tower so that after the heat treatment, and requires the V-notch -40 °C low temperature impact, which we reserve for this powerful metallographic analysis technical capacity.
4) Torque coefficient: the adjustment and control of the torque coefficient, we have rich experience.

[Quality Policy]
Our policy is honest reputation, success by first class quality, continual improvement, seeking better performance.
[Quality Assurance]
1) Use the top grade alloy steel, carbon steel as raw material, through ultrasonic flaw detection, chemical composition analysis, spectroscopic analysis, mechanical property test and spark discrimination detecting, completely rejects any mixed raw material, and keep the material selection complying to Standard requirement.
2) For the lager size bolts which diameter is more than M36, we have farinfrared temperature measuring and controlling device to make sure the good head forming of larger size bolts. For the bolts which diameter is less than M36(including M36), we use multi-station auto cold forging production line of imported HBF-438 and domestic Z47-24/4 machine to ensure bolt size, surface smoothness and conform to the standards.
3) For blade bolt, T-style nut,Embedded bolt extender, we use the advanced CNC processing equipment to ensure the processing precision of products.
4) After the heat treatment, bolts will be processed the metallographic inspection, magnetic particle inspection and hardness nondestructive sorting according to the company's inspection standards for products to ensure mechanical performance 100% qualified.
5) For mechanical properties inspection of the Boltass kit, we use the tensile testing machine (300-5000 KN), low temperature impact testing machine and various hardness tester in order to ensure that the test accuracy. For the torque coefficient testing, we use the advanced intelligent torque coefficient detector (10000N·M~30000N·M) to guarantee that the test data are accurate and reliable.
