Notice how we cut the tapered end (the pointed end of this part) right off. Compare to CNGreen's part above with the crack in it
The original Trigo part as a very sharp area where the thread starts (the taper area). The problem is, as that area gets thinner and thinner the steel obviously gets weaker and weaker. Cutting the thread into the part only exacerbates (I learned that word from Jamo
) the problem. Then you torque the boogers out of that thin little starting thread and BAD things start to happen. That first thread will "pull" out and raise up. It will raise up where it is the weakest--right at the end of the thread. That weak area will raise up (remember, only on one side now--right at the beginning of the thread as it only starts in ONE area) and it will cause the pin to tip!
Sounding familiar???
So, we trimmed the point off (remember CNGreen's crack in the taper) and then deeply deburred the thread so it could not pull. This becomes a very important object lesson. Many times you can REMOVE material from a part and make the part a STRONGER part. Here is a perfect example.
Now you know why our parts cost so much. We try to think about everything. Thinking takes time; deburring takes time, programming takes time, finding the right alloy takes time; you get the point. You can purchase cheap parts...but sometimes (well, usually) it will come back to bite you on the bum bum.
Notice the large nose radius on the taper.
