Thread Pitch Chart - Portland Bolt
Because of the larger tensile stress areas, they have high tension strength. However, a longer engagement is required for fine thread applications than for coarse series threads to prevent stripping. 8 – Thread Series (8UN) is the specified thread forming method for several ASTM standards including A193 B7, A193 B8/B8M, and A320. This series ...
Thread Pitch - an overview | ScienceDirect Topics
These are usually represented on an engineering drawing with an M prefix followed by a value indicating the external diameter in millimetres. For example, if a screw thread is designated as M5, it is a coarse pitch thread of 5 mm diameter. However, if a fine pitch thread is used, the M and associated diameter value will be followed by the pitch.

Screw Threads - an overview | ScienceDirect Topics
A square-threaded power screw with a single thread having the pitch diameter d m, the pitch p, and the helix angle λ is considered in Fig. 1.7. Consider that a single thread of the screw is unrolled for exactly one turn. The edge of the thread is the hypotenuse of a right triangle and the height is the lead.
UNC THREAD CHART - Amesweb
UNC thread chart including major diameter, pitch diameter and minor diameter dimensions of UNC screw threads according to ASME B1.1 standard. External Thread Dimensions for UNC Screw Threads: UNC Thread Chart — External Thread Dimensions
METRIC THREAD DIMENSIONS CALCULATOR - Amesweb
In custom use, thread size, pitch and tolerance classes can be independently selected for custom metric thread dimensions calculations. Some important notes from ISO metric thread standards: - External Screw Thread Designation: Nominal Diameter x Pitch - Tolerance class for pitch diameter - Tolerance class for major diameter (M10 x 1 5g 6g)
METRIC EXTERNAL THREAD DIMENSIONS CHART - Amesweb
The external thread allowance may thus be used to accommodate the coating thickness on coated parts. The designation of a screw thread gives the thread symbol, the nominal size, the pitch, and the thread tolerance class (Ex: M6 x 1 - 4g6g). In tolerance class designation, the pitch diameter tolerance is followed by major diameter tolerance.
METRIC INTERNAL THREAD DIMENSIONS CHART - Amesweb
The designation of a screw thread gives the thread symbol, the nominal size, the pitch, and the thread tolerance class (Ex: M6 x 1 - 5H6H). In internal thread tolerance class designation, the pitch diameter tolerance is followed by minor diameter tolerance.
METRIC TRAPEZOIDAL THREAD CALCULATOR - Amesweb
ISO metric trapezoidal thread profile is a thread form with 30° angle of thread which is used for lead screws (power screws). Dimensions and tolerances for metric trapezoidal screw threads are defined in ISO 2901:1993, ISO 2902:1977, ISO 2903:1993 and ISO 2904:1977 standards.
