Blue Origin 'New Sheppard' flights are manned suborbital... and since the PAX have NO crew function the FAA will no-longer award official astronaut wings... Blue Origin wings only.
Blue Origin is principally owned by Jeff Bezos... and New Sheppard is 100% private/commercial venture... paying...
G123... Landing gear systems hydraulics are designed to 'work' with landing gear installed. There are 'iron-bird' mechanical test set-ups for 'whole system testing'... or 'bench tests' for every component of the hydraulics systems for the gear...

d... I could suggest a variety of male replacement fasteners... problem as I see it... your 'old design' seems 'comfy' with the NAS517 style inexpensive, readily available flush head bolts ['screws' generally have most of the shank fully threaded]. In this case the NAS517 has a large 100Deg...
Tug... I used to live near Vandenberg in the early 1980s and had a few friends working there. OH... and when I was a 'runny nosed-Air Force brat'... my USAF dad was deep into the Thor missile program [training missilemen to maintain/launch Thor] in the 1950s.
At VAFB, weather permitting, there...
Hmmmmm... why is this nomination for NASA administrator... and his stated goals... not so much of a surprise...?
NASA Nominee Isaacman Says Plans For Mars And The Moon Are In Play

FYI... NAS517 is an antique cross-recess flush-tension head [XR-FTH] long-thread [LT] low alloy steel [LAS] bolt [1950s]
Obviously You have a need for a structural XR-FTH-LT-LAS Bolt... why not a newer spec fastener? Is this for homebuilts?
Oh Well
One quick point... 160-to-180-KSI is the HEAT TREAT of the alloy steel... not necessarily the tensile strength rating for the entire fastener
Refer to the specifications for 'spec min required tensile/shear strength'. A LOT of elements go into the static and fatigue strength of fasteners.
Ahhhhh... a single recent issue of CCC trying to control SpaceX operations at VAFB for COMMERCIAL ONLY use. CCC has no say-so for the MIL usage/tempo by Space X

WWII was 'won' at a terrible price. The captured technology [documents/knowledge] and experienced-personnel... scientists, engineers, techs, etc [aero, rocket, weapons, etc]... were never going to be simply discarded... 'because' of being a Nazi rank-and-file party member, ONLY... unless...
/NOTE/ Before I give You the technical answer... here is a practical observation.
Have your vendor check the material certification-paperwork and the mil-printed-markings on the raw material. Often a OEM will manufacture a product to a high standard specification then cross-qualify all other...

I re-read Your statements... and several subtle elements finally made me curious/concerned... with Your presentation... Soooo I have to ask...
Are You testing with gaseous/pressurized... OR LIQUID... helium?
Gaseous testing under pressure at most useful temperatures 'is straight-forward'...

TUG... Musk wants to de-orbit the ISS... to get it out of the way... and place his station in-orbit, instead. AND then simply by-pass the return-to-the-moon to focus on man-to-Mars.. his objective. To do all this NASA simply has to be taken apart and placed in the trash-can of history
NOTE that...
