When using the M12 Bolt, you will need to drill a 12mm diameter hole into the substrate and there will need to be a 14mm diameter clearance hole in the item to be fixed in position. Also Know, what size hole do you drill for a 7 16 tap?
| Tap size | Basic major dia (mm) | Drill size (mm) |
|---|---|---|
| M12 x 1.75 | 12mm | 10,2mm |
| M12 x 1.25 | 12mm | 10,8mm |
| M14 x 2 | 14mm | 12mm |
| M14 x 1.5 | 14mm | 12,5mm |
What is hole size for M12 bolt?
Whenever the pitch dimension is omitted from a metric bolt specification then the bolt is always coarse threaded. This example (M12-50) has a diameter of 12mm and a length of 50mm. As noted, the specification of metric bolts includes the definition of thread pitch, but if this is omitted then a coarse pitch is assumed.
What size is M12 bolt?
Size Nominal Thread Diameter; Decimal Nearest Fractional #10: 0.190″ 3/16″ #12: 0.216″ 7/32″ * Nominal thread diameter is measured on the outside of the threads per ASME B18.6.3 For more information about how to measure diameter see our Measuring Fastener Diameter page.

What diameter is M12 thread?
M12 x 25 = 12 mm diameter, coarse thread is assumed (1.75 mm), 25 mm long M12 is a matching coarse threaded nut (To avoid confusion, we always include the thread pitch for both coarse and fine metric fasteners.) If you normally work with inch fasteners, pitch can be a little confusing—pitch is the distance between adjacent threads.

How do you calculate tap drill size?
Tap-drill diameter equals nominal diameter minus thread pitch. For example, drill size for a 3/8-16 thread is 0.375 0.0625 (pitch) = 0.312 in. in diameter, and for a 10-32 thread, the drill diameter is 0.190 0.032 = 0.159 in. (a #21 drill).
How do you know what size drill bit to use?
How to Choose Drill Bits by SizeUse a bit 1/64” smaller than the target hole size for softwoods.Use a bit exactly the same size as the hole when working on other materials.If you're not sure which to select, choose a drill bit 1/64” larger than the hole you wish to create.
How do I choose a drill bit for a tap?
Rules of Thumb A good tap drill is 90% (± 2 pp) of major diameter for fine threads. For metric V threads, the concept of major minus pitch (i.e., the major or widest diameter of the intended screw in millimeters minus the pitch of the threads of that screw in millimeters per thread) yields a good tap drill diameter.
How much bigger should a hole be than a bolt?
Select a drill bit 1/32 inch larger than the bolt diameter for a tight fit hole or a drill bit 1/16 inch greater than the bolt diameter for a loose fitting hole.
Is an M10 bolt 10mm diameter?
If the size is M10 x 25, that would mean that the diameter is 10 mm. Since there is no thread pitch listed, the fastener is assumed to have a coarse thread. The 25 indicated a length of 25 mm. A matching nut would be labeled M10, which also doesn't require a thread pitch since it's a course thread fastener.
