Sharp Tail Screw Die

Selection of screw mould  

The selection of the leading die is very important, the main life depends on the tungsten steel inside, the use of authentic spring protection tungsten steel can effectively ensure the life, the rub wire plate to have a very high hardness, wear resistance, enough strength, a certain impact force, fatigue resistance, the hardness of the strong working part is 59 ~2HRC, if >62HRC prone to fall teeth,  <59HRC easy wear;  Quenched martensite <3 grade;  There should be no decarbonization and low hardness on the working surface;  The surface of the twisted wire plate shall not have cracks, nicks, rust and grinding burns and other defects that affect the performance of the use.  

Can be directly drilled, tapped and locked on the setting material and basic material, greatly saving the construction time without any auxiliary processing. Compared with ordinary screws, it has tough drawing force and high maintenance force, not easily loose after long time locked, safe to use. Especially in the construction, building, housing and all other places on the combination of work. Whether it is cost or credibility, self tapping self drilling screw is the best economic fastener.
