That calming force can change at great deal with lightly lubricated fasteners from the factor new with a light oil, to a thick flat washer wider than most to spread the load place the hole & thread conditions. I run a tap thru every time. Painted and powder coated threaded holes see more fastener failure than any kind. And wheels studs / pins, don’t get me started on torque sticks. Nice colors, real pretty but useless. That is for toque wrenches that are re-certified by the company that made them, like SnapOn. Throw torque sticks onto a welding table, they make the coolest boat anchors. If you use rope makes difference.

It sounds like you have a lot of firsthand experience with the complexities of the torque to tension relationship. When utilizing torque for assembly, it really is all about the friction factors of the total joint. -Randy

What is the proof strength of 6061-T6 aluminum? Or why doesn't 6061-T6 have a proof strength?
@randylammers99583 жыл бұрын
6061 T6 Aluminum does have tensile, yield and elongation requirements that indicate the strength characteristic of the material. "Proof" is simply a predetermined load used in pass/fail testing. Utilize the real minimum requirements listed for the material and determine a safety margin to set a proof load you are comfortable utilizing for your applications.
