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″).
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
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″).
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
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.
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
The magnetic pull of a threaded stud magnetic mounting pad ranges from 7kg (14.4lb) to 22kg (48.5lb).
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.
