What kind of hole is a tapped hole?
A tapped hole, also called a threaded hole, is a circular hole that has been through the drilling and tapping processes. The tapping process adds threads to the walls of the drilled hole.
When to use a bottom tap or plug tap?
● When to Use – A bottom tap is usually used after the plug tap when tapping a new through hole. You should also use a bottom tap if you are threading a shallow blind hole, and you need your threads to go as deep as possible. If your hole is shallow, then you might have to start your threads with a bottom tap.
What happens when you tap a hole in metal?
The tapping process adds threads to the walls of the drilled hole. The process usually occurs in metal where a typical nut and bolt won’t work. There’s a lot to know about tapping holes but keep reading, and I’ll easily explain things so you can get back to building!
What’s the difference between one way and Torx screws?
One way: One-way heads are a variation on the slotted screw. They can be tightened with a standard screwdriver, but they are tamper-resistant because they require special tools for removal. Torx: A torx head has a recession in the shape of a six-pointed star to provide even more surface area for driving.
What do you do with a tapped hole?
That hole is then treated with a treading bit to create threads in the hole for use with a screw or bolt with matching threads to hold a component or attaching the sheet metal part to another component. There are a number of specifications you have to keep in mind when considering tapped holes.
What do you need to know about tapping a screw?
Tapping is the process of cutting a matching set of threads into a piece of metal, plastic, acrylic, or wood. The process of tapping uses two separate tools: the tap which cuts the threads on the inner diameter of the hole, and the die which cuts the threads on the outer diameter of the bolt or screw.

When to use insertion nut for tapped hole?
If you determine that the material thickness for the Tapped Hole does not allow enough turns you may want to consider using an Insertion Nut. This is what amounts to a nut that is actually pressed into the material with knurled ends so that it is forced into the sheet metal or other material.
