Identify TPT-08-1750
These threaded taper pins are the TPT-08-1750 No. 8 reference in plain-finish carbon steel. The recorded thread is external 7/16-20 UNF. The product has a 1.750-inch effective length and 2.438-inch overall length; both dimensions belong in a replacement comparison.
The effective length is not the same as the full end-to-end length. A request based only on an approximate overall measurement can select a different pin than the one shown on the original drawing. Use the complete part number wherever it is available.
Thread and taper are separate features
The recorded nominal diameter is 0.4900 inch, and the threaded-head length is 0.688 inch. The 7/16-20 UNF designation identifies the external thread, rather than the taper diameter. Keep these features separate when checking the mating parts.
This page does not infer an installation-hole tolerance or machining instruction from the nominal diameter. Match the required pin and hole specification from the equipment or fixture drawing. An externally threaded pin should also not be confused with an internally threaded removal style.
Material and finish
The researched TPT-08-1750 is carbon steel with a plain finish. This identifies the listed version and does not imply a plated coating or stainless-steel construction. If the original design calls for a different material or surface treatment, do not assume that the dimensions make the two versions interchangeable.
Check the service environment and original part specification before a purchase. The product illustration is intended to show the general form, not to certify material, surface finish or dimensional tolerances. The written reference and specification govern the availability inquiry.
Comparing threaded taper pins
Have the original pin reference, nominal size, effective length and thread specification available. Next, compare the overall length and the space around the threaded end in the assembly. This is a useful way to catch a length mismatch without confusing the mounting feature with the external thread.
The request covers pins only. It does not include nuts, removal tooling or a machined mating hole. Any associated hardware needs its own verified reference; it is not automatically included because the pin has a threaded end.
