16Pack Rubber Coated Magnets, 30LBS Rubber Coated Neodymium Magnets with M5 Magnetic Assembly Base for Light Bar Mirror Camera Tool(1.69 Inch)

Corrugations never pull straight down. They shake whatever is stuck to a bull bar sideways, over and over, on paint thicker than it looks, across a panel with a curve in it, under a film of bulldust. Sideways is the direction a magnet surrenders first, and none of that is the condition a pull figure gets measured in.

What "30LBS" does and does not tell you

The supplier's sentence is that the vertical magnetic pulling force is 30LBS. The figure appears here exactly as written and is deliberately not converted into metric, because converting it would suggest a precision the source never claims. What is missing is the basis: no steel thickness, no surface finish, no air gap, no method and no standard is named anywhere. Figures like this are ordinarily taken as a straight pull off clean, bare, flat steel with nothing moving. Whether that is how this one was arrived at, the supplier does not say, so read it as a headline number rather than as a rating you can build around.

M5 thread, a 1.69 inch base and a coated skin

Each piece is a round housing measured at 1.69 inch across with six neodymium magnets set inside it and a threaded hole so a bracket or fitting screws in directly. The title gives that thread as M5. Iron plates and nuts are listed as supplied alongside. Around the outside is a covering the supplier calls rubber through most of its copy and nylon in one line, a contradiction it never resolves and never specifies further. Whichever it is, the three purposes the supplier gives for it are keeping the magnet from chipping, keeping it from marking the surface it lands on, and stopping it skating across smooth panels.

Key features

• Coated outer: present to protect both the magnet and the paint it sits against, according to the supplier.
• Threaded mounting hole: M5 per the title, so a fitting screws straight into the housing with no bracket or adhesive.
• Six magnets per housing: the supplier states six neodymium magnets sit inside each 1.69 inch base.
• Hardware supplied: iron plates and nuts are listed as coming with the set.
• Uses the supplier names: cameras, video recorder brackets, light poles, display panels and similar fittings.

Specifications

• Base diameter: 1.69 inch
• Magnets per base: 6 neodymium
• Thread: M5, stated in the product title
• Stated pull: "vertical magnetic pulling force is 30LBS", the supplier's exact words, reproduced without conversion
• Basis of that figure: not stated. No test surface, steel thickness, air gap, method or standard is named
• Coating: called rubber in most of the supplier's bullets and nylon in one of them; the copy disagrees with itself
• Weather wording: the supplier says waterproof and wear-resistant, with no IP figure or test behind either word
• Pack quantity: the title states 16 pack; the supplier's description text gives no quantity at all
• Shear figure, vibration figure, temperature range: none of these appears in the source

What's in the box

• Coated magnetic bases with iron plates and nuts - 16 according to the product title, a count the supplier's description text does not confirm

Where these belong, and where they do not

• Holding force is not a fixed property of the part. It falls away with paint and primer build, with any curvature in the panel, with dust or grit caught under the face, and it falls hardest when the load works across the joint instead of straight off it.
• Anything fitted to the outside of a vehicle that then travels needs separate mechanical retention as well - a bolt, a bracket or a lanyard. Magnetism alone does not do that job.
• Nothing in this set is suitable for holding an object that could come adrift on a public road. A light or aerial that leaves a vehicle at speed becomes a hazard for everyone behind it.
• Keep both the magnet face and the panel clean. A stone chip's worth of grit is enough to cut the contact area down and take the holding force with it.
• Neodymium is brittle and loses strength as it heats. Keep these clear of exhaust and engine bay heat, and clear of pacemakers, cards and hard drives.
• With no shear figure, no vibration figure and no temperature limit given, there is simply no number here to match against a road application.

Coated magnetic bases with an M5 thread, sold on one stated pull figure whose basis is never given. Sound enough on a bench, a toolbox or a work light off the vehicle; anything that travels wants a bolt through it as well.
