Zinc-plated metal disc 20x2 mm

Product detailed description

A zinc-plated steel base 20 mm in diameter and 2 mm thick — a metal disc counterpart in its basic form, without adhesive tape and without a screw hole. You choose the fixing yourself: construction adhesive, seating in a cut-out, or double-sided tape of your own choice. It works with magnets and pot magnets up to 20 mm across. It has no magnetic field.

1. How does this plain zinc-plated version differ from the one with adhesive tape?
   It is supplied as a bare steel base with no double-sided tape applied and no screw hole. You choose the fixing method to suit your application, which is why it costs less than the fitted versions.

2. How do I fix a steel disc counterpart without tape?
   Most often with construction adhesive, with double-sided tape of your own choice, or by seating it in a prepared cut-out. For a screwed joint, choose the version with a hole and a countersink for a countersunk screw.

3. Which magnets suit the metal disc counterpart without tape?
   Magnets and pot magnets up to 20 mm in diameter — as with the other sizes, the magnet should cover as much of the steel base as possible.

4. Does the plain zinc-plated 20x2 mm version have a magnetic field?
   No. It is a steel disc counterpart with no magnetic field of its own, which holds nothing on its own.

5. What is the surface finish?
   Zinc. It protects the steel base against ordinary surface corrosion in a dry environment; for permanently damp operations we recommend protecting the joint additionally.

6. Is it suitable for production and assembly jigs?
   Yes. Precisely because it has no adhesive tape, it is often glued or embedded directly into parts — for example into wooden, plastic and composite panels.
