Are M10 and 3/8 the same?
As George says the CG-5 does use the metric 10 x 1.5. That said, they are very close, the 3/8" bolt is about 0.019" smaller and the pitch's are very close so the 3/8 -16 bolt will thread in the 10mm x 1.5 but the 10 x 1.5 bolt will not fit the 3/8 but..16-Mar-2015

What does M8 mean on a bolt?
The defined diameter of metric bolts is actually slightly larger than the actual diameter of the bolt shaft. So an M8 bolt would have a shaft diameter that's slightly under 8mm which means that the bolt should fit through an 8mm hole.19-Jun-2020

What is a metric tap?
Metric sizes are referred to as thread pitch. Chamfers are the length of the tapering threads at the front of the tap. Both the chamfered portion of the tap and the first full thread beyond the chamfer produce the finished thread of the part.
What does M8 1.25 mean?
For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning the higher the number the fewer threads there are. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.23-Jul-2018
Is 5/16 The same as M8?
Well, quick answer is no. They are not the same and they are not interchangeable, although they can work under certain circumstances. The most important part is understanding the meaning of M8 and 5/16 to refer to the size of a metric screw or bolt, so then we can see why they aren't the same thing!

How do you calculate metric tap drill size?
As a rule of thumb, for Metric threads, the tapping drill can be calculated by subtracting the pitch from the diameter of the thread. eg for an M5x0. 75 thread the tapping drill is 5-0.75mm = 4.25mm. For Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch.

What is a 6-32 tap?
The 6-32 thread starting tap can be used for cutting new threads or to clean up damaged threads in a previously tapped hole. This tap has several tapered threads at the end to guide the tap into the hole and begin cutting threads.
What is tap size?
Thread size is the number of Threads Per Inch (TPI) which is measured along the length of the tap. Metric sizes are referred to as thread pitch. Chamfers are the length of the tapering threads at the front of the tap.
What are form taps?
Just one more little wrinkle is that Form Taps (also called “Roll Taps” because they perform thread rolling rather than thread cutting) need a different sized hole than Cut Taps, and most drill size charts only show drill sizes for Cut Taps. As a machinist, you’re no doubt aware of the many advantages Form Taps have over Cut Taps: 1 Form Taps don’t make any chips. This is a huge advantage when threading deep holes and especially for blind holes where chips can jam up in the bottom of the hole. 2 Form Taps make stronger threads than Cut Taps. What could be better? 3 Better Thread Gaging. Form taps work by cold forming the metal in the hole. Since no chips are made, the likelihood of producing oversized threads is far less than for Cut Taps. 4 Stronger Taps. It just gets better and better-form taps are stronger and less likely to break than cut taps. 5 Longer Tap Life. Form taps, properly used, can last 3 to 20 times longer than cutting taps because they have no cutting edge to dull. 6 Faster Tapping. You can run higher spindle speeds with form taps than cut taps.
Why does material matter?
The material matters because we can afford higher thread engagement in softer materials and we actually need it to increase thread strength. For hard or tough materials, a lower percentage can really help tap life and those materials have lots of strength even at the lower percentages.
How do form taps work?

Is there a drill bit size for taps?
Newsflash: There Isn’t Just One Drill Bit Size for a Tap. Let’s start with an important fact–there isn’t just one drill bit size to use for a given tap size. There are several. Moreover, the size recommended in most drill bit size charts is very often not the best size to use.
Does one size fit all taps?
The same is true of the size recommended on the tap and even the recommended size from the tap manufacturer. Anytime you see just one size being recommended, you know you can do better–one size does not fit all when it comes to tapping. How can that be? Well, it’s actually pretty simple.
Is 100% thread stronger than 75%?
They’re pretty delicate anyway and will wear off quickly. In fact, they contribute surprisingly little strength. Kennametal says a 100% thread is only 5% stronger than 75% thread. But here is the real kicker: That 100% thread requires 3 times the power to tap!
Why do form taps need a different size hole than cut taps?
Just one more little wrinkle is that Form Taps (also called “Roll Taps” because they perform thread rolling rather than thread cutting) need a different sized hole than Cut Taps, and most drill size charts only show drill sizes for Cut Taps.
