How do I know what size nut and bolt to get?
Determine the maximum torque according to bolt (nut) size and grade. Always consult the manufacturers instructions or engineering recommendations when making bolted connections.

How do you determine what size bolt you need?
How to Measure the Size of a Bolt
- Step 1: Measure the shank's diameter. The shaft of the bolt is called the shank, and its diameter is the first dimension used to describe a bolt size. ...
- Step 2: Determine the thread pitch. ...
- Step 3: Measure the length of the shank. ...
- Step 6: Measure the length of the threaded portion of the bolt.
How do you specify bolts and nuts?
The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated "mm"). For nuts, size will appear as diameter and pitch. There is an exception though—if pitch isn't specified, the fastener is coarse threaded.
How do you determine your fitting size?
Measure the Outside Diameter (OD) of your pipe or pipe fitting:
- Wrap a string around the pipe.
- Mark the point where the string touches together.
- Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
- Divide the circumference by 3.14159.
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.
What are standard bolt sizes?
Bolt Thread Sizes
| Size | Nominal (Major) Diameter [in] | Coarse Thread (UNC) |
|---|---|---|
| Threads Per Inch | ||
| #5 | 0.1250 | 40 |
| #6 | 0.1380 | 32 |
| #8 | 0.1640 | 32 |
What are M sizes bolts?
Metric nuts and bolts are commonly referenced using 'M' sizes, for example: M3, M8, M12. ... The number '8' refers to the nominal diameter of the bolt shaft in millimeters. The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters.
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.
How do you classify screws?
General. Fasteners are identified by four or five attributes; Type, Material, Diameter, Length, and Thread Pitch or Count (machine thread fasteners only).
What diameter is an 8 gauge screw?
For gauge to MM conversion
| Self Tapping Screw Gauge (g) | Size (mm) |
|---|---|
| 6 | 3.5 |
| 8 | 4.2 |
| 10 | 4.8 |
| 12 | 5.5 |
