Thread Pitch Chart Thread Pitch ChartThread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter. Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts. Coars...
Eo = pitch diameter at end of pipe; E1 = pitch diameter at the large end of the internal thread and at the gaging notch; L1 = length of hand-tight or normal engagement between external and internal thread; L2 = basic length of effective external taper thread; D = outside diameter of ...
For specific dimensions, see our Thread Pitch Chart Coarse Thread Series Unified National Coarse (UNC) – Coarse threads have fewer threads per axial distance than fine threads and a larger thread form relative to the diameter. Coarse thread bolts are often used in the construction industry becau...

holes. Do not attempt this yourself unless you really know how, because there is the possibility of the peg splitting, as well as the strength of the peg being compromised. It is clearly an irreversible procedure, so there could be problems later on when returning to normal diameter strings....
Minor Diameter is the smallest material diameter of a thread or gear tooth feature. Pitch Diameter is a diameter between the major and minor diameter where the medium area contact with the associated thread or gear occurs.RelatedANSI External Screw Threads Size Chart Unified Screw Threads per.
