The nut is screw cap, it screwed together with bolt or screw arbor to fasten something. It is a component that must be used in all manufacturing machines. According to the different materials, it is divided into carbon steel, stainless steel, non-ferrous metal (such as copper) and so on.

According to the titanium screw manufacturers data, it shows that the titanium nut is a kind of part that closely connected with the mechanical device, according to the the inside thread, the same specifications of the nut and bolt can be connected together. For example, M4-P0.7 nut can only be connected with the M4-P0.7 series of bolts (in the nut, M4 refers to the diameter of the nut is about 4mm, 0.7 refers to the distance between the two threaded teeth is 0.7mm). The products made in US are same. For example, the 1/4-20 nut can only be paired with the 1/4-20 screw (1/4 refers to the diameter of the screw nut is about 0.25 inches, 20 refers to each inch, there are 20 teeth).

Stainless steel: Self locking nut, anti loosening nut, locking nut, four jaw nut, round nut, ring nut, butterfly nut and so on.

Copper product: Copper nuts, inlaid brass nut, insert brass nut and injection brass nut and son on.
