Does Bolt pitch matter?
Fine pitch threads give you more threads per length and therefore more load to be distributed into the base material. This is ideal if you are working with thin materials or when the base materials are softer than the fastener.
What is the standard pitch of a bolt?
Metric Thread Pitch Table

| Standard | JIS | |
| 8 | 1.25 | 1.25 |
| 10 | 1.5 | 1.25 |
| 12 | 1.75 | 1.25 |
What is 1.25 mm thread pitch?
Table 1.

What does M14x1 25 mean?
The firing end of a spark plug threads into the cylinder head. A spark plugs threads are comprised of 3 dimensions: Reach, Diameter and Pitch. When a thread size is expressed in a set of two numbers, for example, 14×1. 25 or M14x1. 25 the first number is the thread diameter and the second number is the thread pitch.
How many threads should show on a tightened bolt?
Threaded fasteners, when installed and tightened, should protrude a distance of at least one thread beyond the top of the nut or plastic insert. Excessive protrusion should be avoided, particularly when necessary clearances, accessibility, and safety are important.
What is the most common M6 thread pitch?
Metric clearance and tapping drill hole sizes.
| Size | Clearance Hole mm | Tapping Drill (std Pitch) |
|---|---|---|
| M5 | 5.5 | 4.2 mm |
| M6 | 6.5 | 5.0 mm |
| M8 | 9 | 6.75 mm |
| M10 | 11 | 8.5 mm |
Does M12 mean 12mm?
Yes. M12 is a 12mm diameter thread. You have to be sure the thread pitch measured in threads per millimeter (1.5 here) is the same as what u need.
Is M8 bolt 8mm?
Hole Sizes for Metric Bolts 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. For example, an M8 bolt with a standard coarse thread pitch of 1.25mm would require a hole of 6.75mm diameter to be tapped.

How is the pitch of a bolt measured?
NOMINAL DIAMETER (NOMINAL BOLT DIAMETER) PITCH (THREAD PITCH) Pitch is the distance from the crest of one thread to the next or the distance from one thread groove to the next, measured from crest to crest. Pitch is also described as the number of threads per inch. DIAMETER (BODY DIAMETER) The smallest or largest pitch diameter…
Is there a pitch chart for lightning bolts?
As fastener manufactures, we got you covered. Bellow are ISO/DIN accepted thread pitch charts for commonly found metric fasteners. Here is Lightning Bolt’s Metric Bolt Thread Pitch Chart. In the Imperial “inch” system, threads are commonly referred to by measuring an inch, and counting how many threads are inside that measurement.
