Frequently asked questions

What is included in the set?

The product title and feature text describe 12 threaded magnets and mention bolts, M5 spring washers, M5 flat washers and M5 nuts. However, the separate included-components field says "no," so confirm the contents of the selected listing before purchase.

What does the 30-pound pull claim mean?

The listing specifies a vertical pull force of 30 pounds on a steel plate. It does not establish that the magnets can safely support that load in every orientation or on every surface.

What thread size is listed?

The feature text specifies an M5 male threaded stud.

Is the coating suitable for outdoor use?

The listing describes the rubber coating as waterproof and says the magnets have corrosion-resistant surface layers. These are manufacturer claims, not a verified outdoor service-life guarantee.
