Thread Manufacturing - Hi-Tech Seals
Thread Manufacturing Not all threads are made equalHi-Tech Seals and Hi-Tech Gaskets offer bolts in a variety of diameters, lengths and threads per inch. All bolts sold are processed using a Thread rolling method. This is a process mainly used to create external threads. Unlike other threading processes, Thread rolling does not remove or cut away any of the blank s material. Thread rolling is a cold-forming process in which threads are formed by rolling blanks between shaped hardened dies. The blank s diameter is part way between the major and minor diameters of the dies threads. As the blanks rotate and advance through the dies, the dies displace the material to form the minor Thread diameter or root. The displaced material is forced radially outwards to form the major Thread diameter or crest. blank diameterthread rolling diework blank1 Die just engages the workpiece2 Half penetration3 Fully formed threadthread diameter Thread rolling diethreadpitchdiameterCut threadRolled threadthreadangleMany industries today prefer Thread rolled bolts for a variety of reasons.
