Overview

Plate + calculates the electrical current required for zinc electroplating fasteners. Enter the dimensions of your bolts, washers, and nuts, and the app computes the total surface area and outputs the amps needed for a successful plating run.

How it works

1. Go to the Input screen and select a fastener type (Bolt, Washer, or Nut).
2. Choose a metric size — dimensions are filled in automatically from the ISO standard.
3. Tap + to add the fastener to your batch.
4. Switch to the List screen to see the total surface area and required current.

Fasteners are saved automatically. Your batch persists between sessions until you clear it manually.
