Standard Of Machine Screw Pitch and Thread Rolling Blank #0183;*CJWinter offers blank and thread roll design as a free service to optimize the thread roll process 10.Blank Diameter Properties o When cutting a thread,the major diameter = the blank diameter of the threads.o When thread rolling,material below the pitch diameter is displaced during cold form process and the excess material is squeezed up THREAD ROLLING DIESThread Roll Dies,Quality of Blank,Improper Die Design,Tilting of Blank,Slippage of Blanks and Condition of Machine.These problems are influenced by Thread Roll Design,Machine,Set-Up,Blank Quality and Specification.(See page 14 for tips on Set-Up procedure and Blank Quality).Hi-Lifes RoLe in Lap pReventionTHREAD CUTTING FORMING- The surface of the dies has the reverse profile form of the thread-Rolling results in a plastic flow of the metal,so the blank for threading has about the pitch diameter (not the crest,as in cutting).This results in 16 25% saving in material - Blank material has Narrow tolerances for rolling.Only EXTERNAL THREADS can be ROLLED.

Standard of machine screw pitch is the distance from the crest of one thread to the next.The major diameter is the external thread diameter after thread rolling processing.Thread rolling blank diameteris the material diameter before thread rolling processing.The metric system is an internationally adopted decimal system of measurement.It is in widespread use,and where it is used,it is the only or most common system of weights and measures.Standard Of Machine Screw Pitch and Thread Rolling Blank

Thread rolling is carried out at much higher speeds than thread cutting.This reduces machine cycle time.The blank is prepared at the pitch diameter of the thread whereas in cut threads the blank is at the major diameter,so that more material is required.The overall effect is THREAD ROLLING GENERAL INFORMATIONSelf- Tapping ScrewsThread Rolling Screws Plastite Standard for short lengths because it allows greater length of threads.Round Thread Cutting Screws Nominal Screw Size Thread Pitch Thickness Hole Size Gage Max Min Drill Size Hole Diam.2-56 18 .0800Screw Thread Design - Fastenalmandatory root radius with limits of 0.108 to 0.144 times the thread pitch.When first introduced decades ago,it was necessary to specify UNR (rounded root) threads.Today,all fasteners that are roll threaded should have a UNR thread because thread rolling dies with rounded crests are now the standard method for manufacturing most threads.
