i know how it feels! have you ever tried to get rusty caliper carriers off of an old volkswagen?! ;) but seriously, they don't provide much detail on these "fasteners", but it sounds like they reinvented the wheel to seal this canister. anyone have more info?

More detailed post from NASA re: the issue with the fasteners: https://blogs.nasa.gov/osiris-rex/2024/01/11/nasas-osiris-rex-team-clears-hurdle-to-access-remaining-bennu-sample/ https://blogs.nasa.gov/osiris-rex/2024/01/11/nasas-osiris-re... > Curation processors paused disassembly of the TAGSAM head hardware in mid-October after they discovered that two of the 35 fasteners could not be removed with the tools approved for use inside the OSIRIS-REx glovebox. > In response, two new multi-part tools were designed and fabricated to support further disassembly of the TAGSAM head. These tools include newly custom-fabricated bits made from a specific grade of surgical, non-magnetic stainless steel; the hardest metal approved for use in the pristine curation gloveboxes. > “In addition to the design challenge of being limited to curation-approved materials to protect the scientific value of the asteroid sample, these new tools also needed to function within the tightly-confined space of the glovebox, limiting their height, weight, and potential arc movement,” said Dr. Nicole Lunning, OSIRIS-REx curator at Johnson. “The curation team showed impressive resilience and did incredible work to get these stubborn fasteners off the TAGSAM head so we can continue disassembly. We are overjoyed with the success.” > Prior to the successful removal, the team at Johnson tested the new tools and removal procedures in a rehearsal lab. After each successful test, engineers increased the assembly torque values and repeated the testing procedures until the team was confident the new tools would be able to achieve the torque needed while minimizing the risk of any potential damage to the TAGSAM head or any contamination of the sample within.

I believe they're Torq-Set. Another demonic fastener forced upon the world by the Phillips Screw Company.
