Magnetic Holdfast Holders

AlNiCo Holdfast Magnets:

The magnetic holdfast is a range of Pot Magnets for work holding, handling and assembly fixtures to provide a high clamping force and positive grip, but not attraction from a distance. Each Holdfast is equipped with a screw down handle because of the exceptionally strong grip of this range of magnets. On each holder the magnetic power is confined to the workface. Magnetic Holdfasts can be used singly or together to make welding and other assembly jigs. Magnet material used is Alnico 5, working temperature is up to 220 degrees C. North polarity in center of holding face and each magnet has a coated keeper. Outer surface except pole can be red (smooth or wrinkle) painted, or coated with Zinc, Nickel or Chrome.

Applications

1. Holdfast magnets can be used as small lifting magnets.
2. In jigs and fixtures and to hold work pieces during wire cutting.
