Shaun Foster Posted March 13, 2004 Share Posted March 13, 2004 Most of our lanterns have the hookclamp atached with only an M10 nut and bolt and I was looking to replace these with wingnuts. I was also wondering what washers to use and in what position. I have found some 9mm dia wingnuts and bolts, are these safe to use or do I need to use 10mm or 12mm. Also, Is it possible to get wingbolts as some of out hookclamps have M10 bolts in making them very arkward to rig. Thanks Shaun Link to comment Share on other sites More sharing options...

And a good hardware store should sell you m10 wingbolts. Link to comment Share on other sites More sharing options...
gareth Posted March 13, 2004 Share Posted March 13, 2004 The other thing with using 9mm bolts is that if you ever want to mount your lanterns on stands, they won't fit into M10 spigots so you'll have to replace the bolt at that point anyway. M10 hardwar is cheap as chips - save yourself some grief later on, fit the right stuff now. Link to comment Share on other sites More sharing options...
Shaun Foster Posted March 13, 2004 Author Share Posted March 13, 2004 Thanks for the Info, Could anyone give me some rough prices, or point me to a website with them on, as I cant seem to see any on AC or flints. Thanks again, Shaun Link to comment Share on other sites More sharing options...
P. Funk Posted March 13, 2004 Share Posted March 13, 2004 you could use the wonders that are nylock nuts instead... Link to comment Share on other sites More sharing options...

Thanks again, ShaunScrewfix - more M10 nuts, bolts and washers than you can shake a stick at! Link to comment Share on other sites More sharing options...
gareth Posted March 13, 2004 Share Posted March 13, 2004 you could use the wonders that are nylock nuts instead...The disadvantage of these soon becomes obvious during a fit-up, when you often need to remove hook clamps from lanterns to mount them on stands, boom arms, etc. With ordinary M10 hardware you can largely do this without the aid of tools, only using a spanner for a final tightening-down. With Nylocks, it's spanners all the way, and consequently much slower. Link to comment Share on other sites More sharing options...
Brian Posted March 14, 2004 Share Posted March 14, 2004 I have found some 9mm dia wingnuts and boltsI very much doubt it. There is no such thing as a M9 thread; M8 yes, M10 yes but M9 no.Are you sure you're not mis-measuring M10? Link to comment Share on other sites More sharing options...

Metro Posted March 14, 2004 Share Posted March 14, 2004 Our supplier for fasteners, tools and engineering equipment is - BML. They have branches throughout the Midlands and are very resonrable for fastensers. Failing that (If your outside Wales or Midlands - Screwfix is as good as any other.

They must be M8 then, I didn't think M9 existed ether but they seem to measure bigger than 8mm, but are definitely not 10mm. I don't think they are imperial ether as they look pretty new. Thanks again for all the info, next job is trying to get some money ;) Link to comment Share on other sites More sharing options...
Andy Mel Posted March 14, 2004 Share Posted March 14, 2004 To top it all off you could then splash out on a wingnut spanner for those random moments!!! (Unashamed plug I feel I must point out!!!) Link to comment Share on other sites More sharing options...

M10 BoltFlat WasherTrunion Arm of the lanternFlat washerSprung washerFlat washerHookclampFlat washerNylon locking nut This way, you don't automatically get a handful of washers if you remove the hookclamp and it is easier to do up the nut (less friction). With Nylocks, you can "pre-tension" the pan, so that it is loose enough to be moved with one hand while up a ladder, but still tight enough to count as locked off; that's the whole point of using the sprung washer, or so I was told.

chhatton Posted March 22, 2004 Share Posted March 22, 2004 Definitely sounds like Whitworth... I know their more English than Metric but Ugh! I hate to disagree with the order... but I'd go for: M10 BoltFlat WasherTrunion Arm of the lanternHookclampFlat washernut (wing/nyloc/standard - whichever takes your fancy) This arrangement will allow the best lockoff possible by the increased surface area contact between lantern and hook clamp... Also bear in mind that apparently (from what I remember at college) most manufacturers won't give a weight loading for a wing nut because it is made from cast rather than rolled steel... (I'm willing to be corrected on this one) Nylocs are great if you happen to have a couple of Andy's handy spanners in your back pocket... (another plug... more beer required!) although Wingnuts are easy to tighten with them as well... Link to comment Share on other sites More sharing options...
