Subliner Pins provide exact alignment of the punch holder, stripper plate and die bock. As the die is closing, the bullet nose of the Subliner enters a precision slip fit hole in the die block. Since the Subliner is pressed into the stripper plate, and is a precision slip fit in the punch holder, accurate alignment is accomplished. Optional Flats on the shoulder help prevent turning when the screw is inserted or removed.

How many are required?

  • For maximum alignment and parallelism, a minimum of four Subliner Pins should be used for each stripper section in the die. This will minimize stripper deflection.
  • For precision alignment only, two Subliner Pins and two Balancer Pins are required to produce the correct stripping action for each spring stripper section of the die.


  • Eliminates need for stripper bolts and are commonly used to support the die spring.
  • Assures parallel alignment of the stripper plate and the die block when the shoulder of Subliner / Balancer extends .003/.005 less than the stock thickness.
  • Aligns delicate and close-fitting punches with stripper plate.
  • All critical diameters ground +/- .0002 and concentric +/- .0002 TIR. Shoulder thickness +/-.001 and length +/-.002.
  • Made of oil hardened tool steel, through hardened 58-61 RC.
  • Available in standard sizes for greater savings and quicker delivery.
  • Made to customer specifications, (Metric or English).
