Brief introduction:

Full-hardened screw is to overcome the screw in the ultra-wear, high corrosion plastic in the harsh conditions of rapid failure and development, the selection of various different performance of the tool steel, through the efficient and stable heat treatment process so that the screw fully obtain wear-resistant, corrosion-resistant performance, multiplied the life of the screw.

Basic parameters:
