Nice little win on ebay :0)
Turbo Mini Forums

won these on ebay, plan to use the 1/4 unf round the gearbox and the 5/16 just generally. All aircraft so should be decent quality.
Not bad for a fiver eh!

I use them for manifold bolts, very very hard stainless

Paul

I seriously doubt it!

I love the high quality look of them, any ideas who would supply them, measured up and some of the 1/4 may be a tad short. they're 1.125 long

Nice find, but have you got the 12 point sockets to drive them?

Ive got a shitload of them, I think they awesome. Do they have the nylon insert?

Yeah got stuff to drive them but not being able to use an open ended might slow things down a bit?
What do the inserts do?
Got a mate who used to do a lot of lock wiring on harriers when he was in the raf so he's gonna teach me the proper way to do it. Should look awsome all lock wired :0)

Some of the ones I have have a slot going along the threaded bit thats filled with nylon. It does the same job as a nyloc nut.

No not got that on them, so clever these aircraft chaps!!!

they look nice. i can't see you need any thing different from standard bolts in the gearbox IMO just wanted to tell you.

This seems to be the only source of these bolts in the UK:

Not sure how you work out the part number and if they are specifically 12 point.

I work at an aerospace company and had a few spare bolts left over from a part I was making. The bolts I erm (liberated) lol fit straight into the carb holding the bottom plate on. Pitty its a different thread to the top ones though.

Good stuff for a fiver.

As Paul says, I too use them as manifold bolts - much easier to get a 12 point thin wall snap-on ratchet ring over.

Got about 100 of these, from 1/4 to 7/16. All from old broken Rolls Royce marine turbine engines !

Yours might even be the better 1/4 and 5/16 UNFJ with the rolled threads. Very strong. If you got the 12 points squish nuts, they're silver plated to prevent corrosion.

If you use regular stainless nuts, you need to lub them up with clean engine oil as they can sometimes suffer from cold-welding where the threads pick up and seize as you're tightening. Best bet is to tighten really slowly.

Loadsa uses.

Minivanless, but reluctantly happy living with the decision. There'll be another one day.

I've used some of these,

they really are very nice!

great for hot places.

one of the benefits of working in aerospace is checking whats 'dropped' on the floor :) got a few of these but need to re-stock soon
