Whitesupraboy2 Posted December 21, 2009 Share Posted December 21, 2009 Im after some M8 button nuts,16mm (20mm may be too big) cheapest and closest ive found so far http://www.screwfix.com/prods/28834/Bolts/Socket-Screws/Socket-Button-Screws-BZP-M8-x-20mm-Pack-of-50?cm_re=SEARCHPROMO-_-M8%20BUTTON-_-28834 and some T Nuts for them. Ive seen there are various types of T nuts. So this is to be used in a metal frame. Preferably I need the type that are effectively a rectangle in size so they dont spin round. Which places are cheap to order from, I need around 200. Never had to order this type of stuff before so not sure where is best. checked screwfit and dont do a 16mmm bolt cheers Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 21, 2009 Share Posted December 21, 2009 They are correctly called button head Allen screws. Have they got to be plated? If they must be shiny you will finder a wider range of lenths in A2 (stainless steel), but they'll cost more. Nut plates are what I think you are after for the captive nuts. Most are the aircraft and race car industry, so well made and expensive, unlikely to be available in A2 or plated. Raceparts keep plain ones, M8 is coniderd huge though, they may not go that big. Probably only in Imperial, not metric. Can you not use Imperial bolts? I may have misunderstood what you mean by T nuts, got a picture of one?

Whitesupraboy2 Posted December 21, 2009 Author Share Posted December 21, 2009 They dont have to be shiney or anything like that. (they are for inside use) These are all the bits I need most are not causing me an issue however 16mm button screws are and so are these t nuts. See pic below Chris, t nut is near the centre; http://www.x-simulator.de/wiki/images/Mr_Burns_Parts_1.jpg Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 21, 2009 Share Posted December 21, 2009 Not come across those, can't you just buy some 6 to 8 mm thick steel strip and drill and tap it, as needed, cutting lengths off as required? Quote Link to comment Share on other sites More sharing options...
TLicense Posted December 21, 2009 Share Posted December 21, 2009 T-nuts as I've seen them before are usually made from an extrusion that is 'T' shaped with the vertical part being wide enough to have a hole drilled vertically through. You would then feed the T-nut into a slotted extrusion which would enable you to position the fixing anywhere along the slot. By their very nature (square or rectangular shaped) they won't spin in the slotted extrusion. Kind of like on a mill bed, you would use the T-nuts to slide along the slots and then screw in the studs for the clamps. We ordered ours through an external contractor so I don't know where he got it from unfortunately. Quote Link to comment Share on other sites More sharing options...
Digsy Posted December 21, 2009 Share Posted December 21, 2009 They are correctly called button head Allen screws. Actually they are called hexagon socket button head screws. Quote Link to comment Share on other sites More sharing options...
