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 5/16 3/8 7/16 1/2 Teknologi dan Rekayasa

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 Teknologi dan Rekayasa

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                                                     Diameter Recommended Torque (N*m) Class 8.8 Class 10.9 5 7 9 6 12 16 8 30 40 10 55 75 100 135 14 160 215 245 335 20 480 650 Teknologi dan Rekayasa

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. Teknologi dan Rekayasa

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

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 Teknologi dan Rekayasa

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 Teknologi dan Rekayasa

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 Teknologi dan Rekayasa

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 Teknologi dan Rekayasa

# could be different due to size of bottle Thread lockers Anaerobic cures after the components are put together Locks Bolts & Studs against Vibration loosening Four colors Use on screws up to ¼ - Purple # 242 Able to Remove ¼ to 3/4" Bolts - Blue # 271 High Strength Hard to Remove 3/8 to 1" - Red # 290 Wicking Grade for Preassembled Parts - Green # could be different due to size of bottle Clean and dry all parts removing dirt, oil, grease and/or any foreign material Teknologi dan Rekayasa

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 Teknologi dan Rekayasa
