Just One Piece. Easy to Install. Save Time During Maintenance.

What They Are: Screw Caps from Noble Die Components are case hardened steel screws that are threaded over their entire length. They have a black oxide finish for corrosion resistance, and have a center hex hole for easy installation with a standard Allen Wrench.

Applications: Die designers use Screw Caps to create spring pockets instead of machining blind holes or spring wells to contain the stripper springs.

Screw Caps are screwed into threaded recesses in the top surface of the punch plate and hold the die springs fast against the stripper plate.

Advantages: Using Screw Caps simplifies and expedites die maintenance. Individual springs within the die can be changed without having to remove the stripper plate.

Should the stripper plate itself need to be removed for die maintenance, the spring pressure on the stripper plate can be relieved by unscrewing the Screw Caps from the top.
