Aluminum Double Hex Head Bolts

Through research and development, Dongtai Huawei has successfully launched aluminum double hex head bolt as per customers' requirements. Compared with ordinary aluminum bolts, the new products have the following excellent performances:

1.    Light weight (according to the density ratio, about 1/3 that of steel);

2. Tensile strength up to Grade 4.8 (the same tensile strength as steel bolts);

3. Torque can be equivalent to A2-70.

In this way, not only can the overall weight of the objects be reduced, but also the fastening effect can be achieved.

With main alloy elements of magnesium and silicon, they exhibits medium strength, good corrosion resistance, good weldability and sound oxidation effect. The products are used in the power industry.
