Product description

Fasteners of our company are formed by deep-processing high-density large-deformation bars and plates. Without the phenomena of thread falling and corrosion, tungsten screw rods and tungsten nuts have good high-temperature resistance, and can achieve firm connection at high temperature. Meanwhile, our company carries out special treatment on the surfaces of fasteners by polishing and sand blasting treatment, so that the products have uniform surface colors and luster as well as more attractive appearance on the basis of ensuring stable using performance of products. All the products passing the inspection are vacuum-packaged.

Fasteners include screws, nuts, pins, rivets, gaskets, spacing pieces, etc.
