The "Spank Nut" nut developed by Otsuka Forming has been widely adopted by the industry.

The "Spank Nut" nut developed by Otsuka Forming has been widely adopted by the industry. The "Spank Nut" nut is characterized by its powerful function in one-side construction and is well received by many industries. It has been expanded. The nut is a type of pull cap that combines the advantages of both a nut and a rivet. With a dedicated pneumatic, electric or manual nut tool, anyone can easily perform nut tightening and loosening. To maximize the effectiveness of low cost and effort.

Product Industion

  Silicon Carbide (SiC) is used quartz sand, petroleum coke (or coal), wood chips as raw material through high temperature resistance furnace smelting made. Silicon carbide is also called moissanite. Silicon carbide devides into Silicon Carbide Sand and Silicon Carbide Fine Powder. The color has green and black.


Black Silicon Carbide containing SiC about 95%, its toughness is higher than Green Silicon Carbide, most of the material used for processing low tensile strength of materials, such as glass, ceramics, stone, refractory, cast iron and non-ferrous metals, etc.


     Green silicon carbide containing SiC is about 97% above, good self sharpening, mostly for processing hard alloy, titanium alloy and optical glass, also used for honing the cylinder and fine grinding HSS Cutting Tools.
