john.r.davies Posted December 25, 2015 Report Share Posted December 25, 2015 You'll note that the good-old nylok is probably the best alternative in this extreme test. https://youtu.be/IKwWu2w1gGk?t=161 John Quote Link to post Share on other sites
Don H. Posted December 25, 2015 Report Share Posted December 25, 2015 Yes, interesting. They sorta skirted past the point that tab washers and lock wiring work, didn't they? Quote Link to post Share on other sites

openroad Posted December 25, 2015 Report Share Posted December 25, 2015 Interesting Simon, i actually recently did a nut and bolt check on a new build, alot of them needed attention ! When will we see Nordlock on the shelves ? Cheers, Conrad. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted December 25, 2015 Report Share Posted December 25, 2015 Don they skirt round lock tabs and wire locking as their implementation is ctime costly and requires skills Conrad they are on the bay http://www.ebay.co.uk/itm/like/181640054072?adgroupid=13585920426&hlpht=true&hlpv=2&rlsatarget=pla-131843260866&adtype=pla&ff3=1&lpid=122&poi=&ul_noapp=true&limghlpsr=true&device=c&chn=ps&campaignid=207297426&crdt=0&ff12=67&ff11=ICEP3.0.0-L&ff14=122&viphx=1&ops=true&ff13=80 do the bolt/nut threads stretch as you undo the things?

Drewmotty Posted December 25, 2015 Report Share Posted December 25, 2015 I've used Nordlocks under extreme conditions on aircraft test rigs and they perform as advertised.......and disassemble with a heck of a crack. Tab washers and wire locking prevent loss of the nuts but even the best installation allows enough movement to considerably reduce clamping force. Quote Link to post Share on other sites
ianc Posted December 26, 2015 Report Share Posted December 26, 2015 Like Andrew, I'm not happy with tab washers and wire-locking because they cannot prevent a small movement and hence a loss of clamping force. Wire locking is useful to prevent loss of the nut/bolt - I use it on the very large hexagon on the underside of the overdrive, and the bolts securing the generator bracket to the cylinder block (because one of the bolt hole goes direct to the inside of the block and can empty a lot of oil if it goes AWOL - happened on my brother's TR3). I prefer nyloc nuts (where a nut is used), or a spring washer or Lock'N'Seal (or both) where a bolt is going into a tapped hole. Ian Cornish Quote Link to post Share on other sites

jean Posted December 30, 2015 Report Share Posted December 30, 2015 I wonder in how far the modern nylocs are heat resistant. In the 70 I removed a lot of nuts and bolts from a DC7C aircraft and I noticed that the inserts on the nuts were all made of fibre or they were fitted with a split top section. They were probably designed to accept quite an amount of heat input. Some of the small bolts are used on my 6... some came from underwing inspection doors/panels and probably have seen the whole world from above.. Quote Link to post Share on other sites
RogerH Posted December 30, 2015 Report Share Posted December 30, 2015 Hi Jean, the split lock nut (nylok without the plastic) are really good but nobody on the high street sells them. They can withstand any temp. The ordinary nylok does not like too much heat at all. There are a number of aircraft fasteners that would work well on out cars.

Roger That'll be Aerotight nuts Roger from LAS or the local exhaust centre where down pipes are often attached by all steel stiff nuts - beware of metric! Moss sell the Philidas type steel lock nuts GHF241 = 1/4, GHF242 = 5/16, GHF243 = 3/8, GHF242 = 7/16 - get the sequence? Cheers Peter W Quote Link to post Share on other sites

graeme Posted December 30, 2015 Report Share Posted December 30, 2015 I think Roger's local supplier has these nuts!! LNZ104, LNZ105, etc http://www.moss-europe.co.uk/nut-stiff-nut-1-4-lnz104.html Cheers Graeme Quote Link to post Share on other sites
RogerH Posted December 30, 2015 Report Share Posted December 30, 2015 Hi Graeme, I wish I had looked at the Moss Cat before posting. But the Moss ones are slightly different to the Aerospace ones. Roger Quote Link to post Share on other sites
graeme Posted December 31, 2015 Report Share Posted December 31, 2015 Hi Graeme, I wish I had looked at the Moss Cat before posting. But the Moss ones are slightly different to the Aerospace ones. Roger Hi Roger, Ha ha, yes, I realise that, as I have a number of very expensive nuts from RR Avon engines in the garage. It's funny how if you put things in a plastic bag with a RR badge on it they suddenly multiply in value. But, the Moss ones should do the job for a TR.
