Knock Out Pins

are used at several industries and has a common usage in the metal industry. Most of workpiece are as Injection Moulding, Punching dies, Screw heading machineries. Heat coated and grinded knock out pins shaft hardness degree is 60-62 Hrc and the head hardness of 40-45 Hrc degree. They are particularly suitable for die cast tools pressure. According to request pvd(Tin or Tialn coated) knock out pins are available in our stocks for immediate shipping.

Metal: 1.3343 High Speed Steels (HSS)

Hardness Level

Shaft: 60-62 HRC(Rockwell)

Head: 40-45 HRC(Rockwell)

Surface: Grinded , Nitrided, Heat threated and polished.

Above informations are general knock out pins for extra hardness and toughness we suggest to use M42 material ejector pins with additional cobalt added.

Planetary Thread Rolling Dies

operates much more faster and knurls of the screws than regular flat type thread Rolling dies. Planetary Rolling dies exist with 3 pieces which is one circular die and 2 pieces quarter moon or 3 pieces quarter moon. In our stocks we have M2 or M42 material nitrided(oxidized) dies, those planetary thread Rolling dies makes properly knurling of the screws with quantity of 6 or 8 million pieces of metric screws.
