Engineers - Tap and Die?

[Unknownsoldier]

Hi Guys,

Anyone here have any engineering experience who could rethread a 7/16 bolt to M10X1.25?????? I'm happy to pay for postage etc. I just need 2/4 bolts rethreading for my car and don't have a tap and die set nor the knowledge of how to do it.

Any help appreciated guys,
Tom

Hi Tom, would be hard to do , as 10mm is 3/8, why not go online , or local and get the bolts you need, 1.25 is and standard metric pitch,................... or do you need bolts with a shoulder

Just text messaged my step dad, hes a professional (retired) toolmaker / engineer.

Will get an answer soon, I hope.

He says no, it will only work the other way round.

Thanks guys, I am trying to fit some harnesses and therefore need 8.8 m10x1.25 collared eyebolts.... which no one makes apparently... I have one set on the way from a friend who had someone ages back alter them... but otherwise :/

So you guys reckon i'm onto a loser here?

I personally dont know. step dad reckons so.

There is a great place on one of my local industrial estates, it sells specialist fittings and fasteners, im that way tomorrow so i will call in and ask them for you.

Ive been into the place i mentioned. I questioned them quite intensely and they all said that it cant be done and the only m10s you will find will be 1.5 pitch.

Sorry mate, I tried.

Thanks mate will have to do soem reworking of the interior then.... might need longer bolts to fit to the sides and utilise the runner bolts I have elsewhere

Thanks for your help though mate

Have you considered fitting thread inserts and getting screws/bolts to fit?

Just a thought. Have you tried contacting 'old' motor cycle suppliers. From memory, M10 used to be available with 1.5 andd 1.25 thread..... I have an old Norton and a full set of taps and dies - Whit, BSF, BA, BSF and have been making up nuts, screws, bolts etc for a while. What has been suggested about using a helicoil etc also sounds sensible - depending on the location.
