Our company has developed a new Single Strew .Its surface is compounded with china. So compared with other screws
this new product's surface hardness has already reached HRC70.For some special material,e.g. Magnetpowers, Copper Power, Bakelite and so on, its life is usually 5-10 times longer than normal screws.
And our company has owned a patent right granted by China Paten Office. So what's the problem is to intitle this projuct a proper English name. And would you please give us some reference??
If you have any good idea please contact me
