hi just got the above deck - ive got loads of headshell bolts but non the correct thread -any help please
I've never had an AR77XB but you probably need the same screws that were used on the XA and XB. I've attached a pdf drawing that shows the hardware that was included with XA and XB headhshells.
#3-48 screws may be a challenge to find locally but McMaster-Carr has them.

I've also attached cartridge mounting instruction from AR.

thanks ronaldw441 - it turns out 4-40 screws for original head - metric 2.5mm if using a replacement head
Interesting..... AR must have changed the headshell between the XB and XB77 models. I just re-checked some of my XA and XB headshells (I have 14 of them) & they definitely require #3 - 48 screws.
Hope you have a happy new year.
no i mean all original are #3-48 - sorry i got that wrong - i ordered brand new copy - best audio - they are 2.5mm - handy
would you happen to know original mat thickness - im on 3mm felt - as it affects arm angle - or what size do you use - cheers HNY
Good. M2.5's are easier to find then #3's, even on this side of the pond. I've seen the Best Audio headshells on Ebay. They look like a quality product. Much nicer than the 3D printed headshells.
Good luck with your AR.
What cartridge will you mount or what is the dimension of the mounting slot as shown on the attached drawing? I'll see if I have anything useful (no promises).
HI your very kind to look for me - 5.25 mm for the cart - any above that i can trim - aluminum only many thanks
Here's a source for small fasteners:

Also, you can use brass screws or 303 Stainless Steel screws.

Me too. Usually 8 a year. 2 at my youngest grandson's birthday, 2 at the other grandson's birthday, 2 at Thanksgiving and another 2 at Christmas. Only had 7 last year (2023). Don't know what went wrong.......
Unfortunately I have few aluminum #3 screws & I want to keep the few I have since half of my 14 AR headshells are without cartridges. Sorry I can't help.
