Place the magnet wherever it’s convenient, and keep it in its Rivet Nut tool, which you can purchase separately (I will review them below). That is a solid, CNC-machined bit. It seems precise in its sizing and punched through heavy aluminum easily. I’m not one to argue with my projects. However, searching through a collection of drill bits to discover one that is “almost right” and then be a part of the project fighting over it is too much work for me.

Buyer’s Guide
How Does The Rivet Nut Work
Rivet nuts allow the use of fasteners within places with less thickness and uncomfortable positions. Although not all of these tools are identical, there are some common elements among them.
When the hole of the right dimension is approximately similar to the size of the rivet, the rivet’s fastener component is placed into it. Next, the manual or automatic tool inserts into the bolt by turning it within the fastener while simultaneously tightening the opposite side of the metal. Finally, it creates threads that bolts to connect to the bolt, with blind rivet bolts being inverted versions that have the bolt connected, allowing it to be threaded on various sheets of metal.

Riveter Size To Metal Thickness
The size of the rivet you choose is crucial, as one that is too small will not work when working with particularly thick sheet metal. Unofficial guidelines dictate that rivets use a metric measurement system, with M3 sizes that work well for thicknesses exceeding 1.5 millimeters; M4 up to 2.5mm; and M5 upwards up to 3.0mm. Each increment in the size of the rivet adds 0.5mm of thickness.
Manual Vs. Automatic
A high-quality hand-riveter can get you far, but it can also be limited to bigger projects. Rivnut(r) guns and attachments for drilling be used to tackle big projects, but they are not always necessary for homes.

Rivnut Tool Assembly
There are five steps to making the riveting tool.
In the beginning, you’ll have to retract the slide completely before you place the riveted nut finger in the stud.
There must be a hole in which to put an adjustable rod. However, every rod is unique. Next, the screw which slides up the ramp needs to be shut between 0 and 1/4 inch. Last, you should apply a small amount of oil to the tool to simplify the operation.
