Width

Width of a threaded stud magnetic mounting pad 40mm and 102mm The width of a threaded stud magnetic mounting pad refers to the size of the two shortest sides and can range from 40mm (1.57″) to 102mm (4″).
Yellow taxi with a sign with advertisements, with labelled magnetic mounting pads holding it on A narrower threaded stud magnetic mounting pad is particularly useful for holding thin non-ferromagnetic material, such as a small sign.

This is because the magnetic mounting pad will be hidden underneath, which will make it more visually appealing.

Depth

Threaded stud magnetic mounting pad depth 7mm and 32mm The depth of the threaded stud magnetic mounting pad is the distance between the bottom of the magnet and the top of the back plate, excluding the threaded stud.

It can range from 7mm (0.28″) to 32mm (1.26″).

Thin threaded stud magnetic mounting pad A thinner threaded stud magnetic mounting pad will be less visible to the user making it better for a car-roof sign as there will be no gaps between the car roof and the sign.

Length

Length of a threaded stud magnetic mounting pad 60mm and 127mm The length of the threaded stud magnetic mounting pad can range from 60mm (2.36″) to 127mm (5″).

A longer magnetic mounting pad will be beneficial for long advertising signs as the magnet will be able to hold a greater proportion of the sign securely.

Two threaded stud magnetic mounting pads, one with a 16mm threaded stud and the other with a 32mm threaded stud The threaded stud in the threaded stud magnetic mounting pad is M6 (this stands for 6mm in diameter), and can have a length ranging from 16mm (0.63″) to 32mm (1.26″).

A longer threaded stud can be used to attach thicker non-ferromagnetic materials to the magnetic mounting pad.

Magnetic pull

Threaded stud magnetic mounting pad magnetic pull with a sheet of steel and pull force The magnetic pull of a threaded stud magnetic mounting pad ranges from 7kg (14.4lb) to 22kg (48.5lb).
Wonkee Donkee says "The magnetic pull is the maximum weight of ferromagnetic material the magnetic mounting pad can hold, this is not determined by its overall size. This means that a large magnet does not necessarily have a larger magnetic pull than a small magnet"
Yellow taxi with a sign with advertisements, with labelled magnetic mounting pads holding it on The larger the threaded stud magnetic mounting pad is, the larger the non-ferromagnetic material it can hold.

This is because the larger the overall area of the threaded stud magnetic mounting pad is, the greater the contact between the magnet and the ferromagnetic material, which increases its holding capabilities.
