NoirBass Posted April 25, 2016 Share Posted April 25, 2016 (edited) Does anyone know where I can find, or what size screw to buy to to attach my Boss 1/2u units to a rack tray. I managed to get hold of a RAD-50, but it has no screws. The threaded mount is the recessed one in the bottom of the Boss unit: [attachment=217753:Boss Screw.jpg] Edited April 25, 2016 by NoirBass Quote Link to comment Share on other sites More sharing options...
Matt P Posted April 25, 2016 Share Posted April 25, 2016 (edited) is there not something stamped into the unit next to the hole? I've seen the screw spec stamped into some units. Assuming that this is a Japanese Unit I'd expect it to be a Metric screw, measure the diameter of the hole and round up to the nearest millimetre, (i'd expect it to be 4mm or so), then just pick up a selection of (M4) screws, shine a light into the hole and see how deep it can go, or use a cocktail stick to judge how far the screw can go before it hits something, then fit a slightly shorter screw so it doesn't short on something inside.

NoirBass Posted April 25, 2016 Author Share Posted April 25, 2016 HI Matt ,thanks for your reply. I have an old Alesis unit that uses a similar system and it does have the screw size stamped into the case, so good call there. The Boss units I have don't have anything stamped into the chasis. On measuring it, it appears to be 2mm in diameter. Good advice on finding the length too. Quote Link to comment Share on other sites More sharing options...
BigRedX Posted April 25, 2016 Share Posted April 25, 2016 IIRC the screw length is fairly short - as the indent in the rack tray plays a large part in holding the unit in place. Quote Link to comment Share on other sites More sharing options...

[/quote] Agreed, Having measured with a cocktail stick as suggested, the hole goes right thorough to the other side of the case, suggesting there is also a hole in the main pcb. That said, I think 10mm would be more than enough. I'm assuming something like this will work: https://www.orbitalfasteners.co.uk/en/products/m2x10-pan-pozi-machine-screw-mild-steel-bright-zinc-plated-din-7985?utm_medium=google_shopping&utm_source=google&utm_campaign=google_shopping&gclid=CjwKEAjwgPe4BRCB66GG8PO69QkSJAC4EhHhRMIeZwuFikz8HogWlMG0Tfe2h2Ug1eXpYTkIB0pn9xoCcWjw_wcB Edited April 25, 2016 by NoirBass Quote Link to comment Share on other sites More sharing options...

When I said fairly short I meant 5mm max. Quote Link to comment Share on other sites More sharing options...

NoirBass Posted April 25, 2016 Author Share Posted April 25, 2016 Right, For future reference I ordered these: M2x5 pozi pan machine head screws https://www.ebay.co.uk/ulk/itm/361516262481 I'll post the results when they arrive. Quote Link to comment Share on other sites More sharing options...
NoirBass Posted April 27, 2016 Author Share Posted April 27, 2016 (edited) They have arrived and are not the right size😟 These seem tiny, M3's needed perhaps? Edited April 27, 2016 by NoirBass Quote Link to comment Share on other sites More sharing options...
BigRedX Posted April 27, 2016 Share Posted April 27, 2016 I sold the last of my Boss half-rack gear a while back, but IIRC the screws required to hold them in place in the rack tray were short and stubby with an fairly wide head - not a standard looking screw. Might be worth getting in touch with [url=http://www.roland.co.uk/support/repairs_spares/]Roland UK[/url]. Quote Link to comment Share on other sites More sharing options...
Matt P Posted April 27, 2016 Share Posted April 27, 2016 somehow I didn't get notifications from this thread, M3x8 pan head screws will probably be about right, it might be worth picking up a small selection box of m3 and m4 nuts and bolts, a washer between the screw had and the tray is a good idea too.

NoirBass Posted April 27, 2016 Author Share Posted April 27, 2016 After some delving around on the internet for a while, I discovered that the Roland TD-5 uses a couple of M3x6 screws to attach to a RAD-50. I have ordered some and a few washers. We'll find out in a couple of days if it's the correct size. Quote Link to comment Share on other sites More sharing options...

M4x8 are the final ones I'm going to buy and then it's just getting gaffered to the tray! Edited April 28, 2016 by NoirBass Quote Link to comment Share on other sites More sharing options...
stoo Posted April 28, 2016 Share Posted April 28, 2016 I've got one of those for my VF-1... it's currently out at a mate's studio and I won't be over there again until next week. I might just have the second screw that came with the rack tray tucked away in the VF1 box though, which is at home somewhere. I'll have a look when I get home Quote Link to comment Share on other sites More sharing options...
NoirBass Posted April 29, 2016 Author Share Posted April 29, 2016 Success! 3rd time lucky, it's an M4x8 pan pozi screw should anyone else need to do the same. These fit the VF-1, SE-70, and the Boss Microrack series. Quote Link to comment Share on other sites More sharing options...

I have plenty of the correct size now though.😄 Edited April 29, 2016 by NoirBass Quote Link to comment Share on other sites More sharing options...
