Solstace Posted September 14, 2011 Share Posted September 14, 2011 I've been a tool, and lost our tool to get into a particular rack in one of our buildings. On top of this, I'm having a bear of a time looking on Google to find a replacement. So - anyone happen to know what these bolts might be called, and where I might get a tool I can use to get them out? http://abstractnoise.files.wordpress.com/2011/09/photo.jpg (Think once I do get them out I'll replace them with a more standard solution for which we have several tools!)

grizzly Posted September 14, 2011 Share Posted September 14, 2011 They look like they might be these: RS 526-754 The tool to undo them is shown bottom right Link to comment Share on other sites More sharing options...
portytech Posted September 14, 2011 Share Posted September 14, 2011 They look awfly like torx fixings but not recessed, you may be able to use vice grips to undo them, if not speak to your local supplier of tools and fasners (I think I may have even seen them in the screwfix catalog) they tent to hold such tools.

Jivemaster Posted September 14, 2011 Share Posted September 14, 2011 Just one of the many forms of "security" screws. Probably the tool is available from Maplin CPC and your local electronics shop, The link above (RS ) links on to the driver through RS. Is there a reason for use of security screws in that particular rack. Be sure that the rack is threaded for M6 before you commit to replacing these with pozi M6 screws Link to comment Share on other sites More sharing options...
mutley Posted September 14, 2011 Share Posted September 14, 2011 One solution to remove them is to get a cheap "rotary tool" (ie; Dremel copy), with a cutting disc in it, and grind slots in the heads to use a flat screwdriver. I've used this solution many times in undoing weird security screws.If you can't find a cheap Dremel copy, you could just put the cutting disc attachment in a mains drill...

Andrew C Posted September 14, 2011 Share Posted September 14, 2011 They are definitely sold by RS. I've used them on the racks in classrooms here. Three sizes available, those look to be size 3, the largest. Link to comment Share on other sites More sharing options...
Guy Tec Posted September 14, 2011 Share Posted September 14, 2011 I think they are called system zero and they have Their own removal tool ! Link to comment Share on other sites More sharing options...
emsgeorge Posted September 15, 2011 Share Posted September 15, 2011 def system zero. RS do a hand held screwdriver, and used to do a drill bit attachment (although cant see them any more on their site) We use these to stop people removing amps, limiters etc in clubs. Some of the dj's have a nasty habit of bypassing the limiter. If they are torqued up to a decent level, then they are a complete mare to get off without the correct tool.

dbuckley Posted September 15, 2011 Share Posted September 15, 2011 You can get screw bit kits which have all the different security and other unusual stuff in them. A decent investment. Link to comment Share on other sites More sharing options...
Sam Jelfs Posted September 16, 2011 Share Posted September 16, 2011 They look very much like a torx bit - wouldn't be surprised if a torx socket would fit. Link to comment Share on other sites More sharing options...
Andrew C Posted September 16, 2011 Share Posted September 16, 2011 They look very much like a torx bit - wouldn't be surprised if a torx socket would fit. It is System Zero. Not Torx. It is a mirror image, with the splines inside the driver, rather than outside. If you see what I mean... Link to comment Share on other sites More sharing options...
kerry davies Posted September 16, 2011 Share Posted September 16, 2011 Torx = male type driver. System Zero = female type driver. Link to comment Share on other sites More sharing options...
Sam Jelfs Posted September 20, 2011 Share Posted September 20, 2011 Andrew C / Kerry - Thats funny, I have a rail full of female Torx sockets (called External Torx, using a number beginning E to designate the size, instead of T) - http://www.machinemart.co.uk/shop/product/details/pro44-14-pce-tx-bit-set?da=1&TC=SRC-torx - Used quite commonly on modern cars. :) Link to comment Share on other sites More sharing options...
