 |
A through hole magnetic mounting pad is a type of magnetic mounting pad which can be attached to a non-ferromagnetic object through the use of two through holes. | |||
 |

 |
A through hole magnetic mounting pad can be attached to a non-ferromagnetic material with the help of two screws. The screws are drilled into the through holes and the non-ferromagnetic material, to create a secure hold. | |||
 |
The best type of screw to use is a flat head screw, which has a gauge (shank diameter) of 3mm (0.12″) or 4mm (0.16″). | |||
 |
This is because a magnetic mounting pad has a through hole diameter of either 4mm (0.16″) or 5mm (0.2″). A screw with a gauge of 1mm (0.04″) less than the through hole will provide a secure fit e.g. use a 3mm (0.12″) screw for a 4mm (0.16″) through hole. | |||
 |
A through hole magnetic mounting pad is particularly useful for holding small non-ferromagnetic materials such as a small taxi sign.
This is because the overall area of the through hole magnetic mounting pad is a lot smaller than the threaded stud magnetic mounting pad. |
|||
 |
Also, a pair of screws would not be able to hold the material as securely as a threaded stud and nylon insert lock nut. This is because a screw can work its way loose, whereas a nylon insert lock nut cannot be moved, once it has been attached, without a sufficient level of force. | |||
