Thread Terminology External Thread A thread on the external surface of a cylinder screw or cone Depth of Thread The distance between crest and root measured normal to the axis. Root Pitch External Thread Major Pitch Ø Minor Ø Ø Thread Angle Helix Angle Major Diameter The largest diameter of a screw thread. Pitch Diameter On a straight thread, the diameter of an imaginary cylinder, the surface of which cuts the thread forms where the width of the thread and groove are equal. Minor Diameter The smallest diameter of a screw thread. <strong>Threading</strong> Technical Data Pitch Crest The distance between corresponding points on adjacent thread forms measured parallel to the axis. This distance can be defined in millimeters or by the tpi (threads per inch), which is the reciprocal of the pitch. Helix Angle For a straight thread, where the lead of the thread and the pitch diameter circle circumference form a right angled triangle, the helix angle is the angle opposite the lead. Nominal Diameter The diameter from which the diameter limits are derived by the application of deviation allowances and tolerances. Internal Thread A thread on the internal surface of a cylinder or cone. Straight Thread A thread formed on a cylinder Taper Thread A thread formed on a cone Left-hand thread Right-hand thread A thread which, when viewed axially, winds in a counterclockwise and receding direction. All left-hand threads are designated LH. A thread which, when viewed axially, winds in a clockwise and receding direction. Threads are always righthand unless otherwise specified. The Helix Angle b Helix Angle Lead þ x Pitch Diameter Lead The distance a threaded part moves axially, with respect to a fixed mating part, in one complete revolution. The lead is equal to the pitch multiplied by the number of thread starts. 119
Machining a Multi-Start Thread A thread in which the lead is an integral multiple, greater than one, of the pitch. A multi-start thread permits a more rapid advance without a coarser (larger) thread form. First Start Machined Second Start Machined Third Start Machined (Final, 3 Starts Thread) <strong>Threading</strong> Technical Data Pitch Pitch Lead Pitch Lead Lead = 3 x Pitch Insert Profile Styles Partial Profile Full Profile The V partial profile insert cuts without topping the outer diameter of the thread. The same insert can be used for a range of different thread pitches which have a common thread angle. Full Profile for Fine Pitches The full profile insert will form a complete thread profile including the crest. For every thread pitch and standard, a separate insert is required. Semi Full The full profile for Fine Pitches will form a complete thread. The topping of the outer diameter is generated by second tooth. The Semi profile insert will form a complete thread including crest radius but without topping the outer diameter. Mainly used for trapezoidal profiles. 120
