4. SYSTEMS OF THREAD MEASUREMENT
ENGLISH SYSTEM
System of thread measurement uses a fractional system to determine thread diameter when 1/4” or larger.
Each diameter increases by 1/16” up to about 1/2”
Thread diameters of 1/4”, 5/16”, 3/8”, 7/16” 1/2” are most commonly used
ENGLISH SYSTEM
These diameters are the most commonly used.
1/4 5/ / / /2

5. SYSTEMS OF THREAD MEASUREMENT
METRIC FASTENERS
SIMILAR TO ENGLISH SYSTEM
THREAD DIAMETER IS EXPRESSED IN MILLIMETERS (mm)
THREAD TYPE IS DIFFERENT
THREAD SIZE IS DETERMINED BY MEASURING THE DISTANCE IN MILLIMETERS FROM CREST OF ONE THREAD TO CREST OF NEXT ONE.
Example 1.00, 1.25, AND 1.50

6. Thread Designations for Metric
To write out Thread designations for Metric bolts first you give the Diameter then the Thread Pitch then the Length. Only this time it should be in millimeters
D X TPI X L
M12 X 1.50 X 60
You can always add the Class (grade) of the bolt. Such as 4.8, 8.8, 10.8
Metric Recommended Bolt Torque

7. STUD STRENGTH STUD REMOVAL
One way is to jam two nuts together and then put the Wrench on the inside one and turn it out.

8. How to measure a bolt
A. Pitch C. Diameter D. Thread length E. Screw length
F. Threads per inch G. Head size

9. THREAD PITCH Thread pitch gauge
From 0-1 shows that you have 7 TPI Threads per inch. (US standard)
Metric you measure the pitch, from top of thread to top of thread like # A
Used to find how many threads in an inch
come in metric and standard
Screw pitch gauge common name of this

10. Thread Designations
To write out Thread designations for US bolts first you give the Diameter then the Thread Pitch then the Length
D X TPI X L
½ X 13 X 2 ½
Take a bolt and give me the Thread designations for it.
You can always add the grade of the bolt. Such as grade 5

11. Thread Designations Then we measure the Length. D X TPI X L
Next we measure the Thread Pitch.
D X TPI
½ X 13
Then we measure the Length.
D X TPI X L
½ X 13 X 2 ½

12. Thread Designations for Metric
To write out Thread designations for Metric bolts first you give the Diameter then the Thread Pitch then the Length. Only this time it should be in millimeters

24. BOLT PAINTING
Many cars left the factory with painted bolts, nuts and other assorted fasteners.
The problem for the garage restorer is that these freshly repainted pieces chip and mar easily.
So do what the factory did: Bake the paint on. An old toaster oven is perfect for this task--just set the oven to 325 degrees and let the parts bake for a half-hour.
This process sometimes changes the color of paints
