    I'm in need of 3 M7 bolts, can be 0.75 or 1.0 mm threads. They need to be 25mm minimum length and be either hex/torx cap head style. They can't be a normal bolt head as they go inside a deep narrow hole.


    Thanks for any help or stupid posts that follow:)

    Thanks guys, I didn't realise how uncommon M7 was. I might see if I can stretch to M8, if not I'll have to go for some expensive M7 ones.
     
  8. Using a M6 Recoil insert would let you keep the correct bolt size and the drill is going to be considerably less than 8mm....the kit will probably work out less than the cost of M7 set screws....just a thought...:) An M7 tap may well cost an arm and a leg as its a non preferred size

    I'll look into this. :thumbsup:
     
  10. Very easy to use as they come complete. Ive bought them off fleabay in the past...plenty of stockists.
     
  11. I have M7 taps, 1.0 & .75 if needed

    If I went the helicoil route, can you put more than one coil in the the damaged hole. I've never done one before. They all
    list them as being 8.0mm long which doesn't seem enough thread to me.
     
  14. is it going into ali ?

    Yes, Ali cylinder head/ piston chamber
     
  16. Wurth timesert much better than helicoil and they are available in different lengths
    pricey but permanent and wont wind out like helicoil can
     
  17. was their stainless ones originally ?
     
  18. cant you just use an aluminium rod to weld the hole over and re drill / tap?
