Specifications: Pin: 0.055 Dia. x 3 Pin Hole: 0.062 Spring: 0.162 Dia.x 2 3/4 Spring Hole: 0.166 Screw: 10-32 x 3/16 Each UNIKIX(tm) Spring Pin consists of a hardened steel rod soldered to a compression spring. A UNIKIX(tm) Spring Pin can eject a sheet-metal part after cut-off. This can prevent the sheet metal from being held against the stripper by stamping-fluid surface tension. UNIKIX(tm) Spring Pins can prevent slug pulling. This can prevent the slugs from being pulled upward out of the matrix when the die opens. The spring-pins eject the slugs by overcoming the stamping-fluid surface tension which can cause the slugs to adhere to the ends of the punches. A UNIKIX(tm) Spring Pin can also delay the actuation of an electrical switch.
