Torque spanner/extenders - anyone know where I could buy some?
alistairolsen - 23/6/12 at 07:29 PM

I'm looking for a set of these (or a single one in 13mm if not)



Does anyone know where might sell them? Best I've been able to find are short crows foot spanners?

If not I can always buy some cheap spanners and weld nuts to them but thats a bit shonky!

Cheers

Dunno but I'm intrigued how much do they multiply the torque by?

They're not really designed to increase torque, they're designed to torque up nuts where a standard socket won't fit due to the thread its going on to. You're even meant to use them at right angles to the torque wrench so the torque setting is still accurate.

I remember looking for one to tighten up a front suspension nut, having to counterhold the damper piston with an allen key meant that you couldn't just use a socket. I thought Cromwell sold them, but I've just had a quick look and can't see them.

Yup, it would appear so...

And now I know the proper name for them;

Cheers guys. There seems to be some ambiguity over the names they are given and whether folk have heard of them or not!

I need to torque up the cylinder bolts on my bike and they came undone with a ring spanner....

Sadly there's nothing locost about that lot! I suspect Im back to a cheap spanner and break out the welder

Using them will corrupt the torque reading.

I was taught that if you keep them at right angles to the torque wrench, the torque at which the head 'clicks' will stay the same as you're not increasing the length of the lever.

Alternatively, you can keep it inline with the torque wrench and calculate how much lower you need to go on the scale based on the increased length.

Is there enough room to drop on a box spanner (like a tube with a hexagonal of different size on each end), and then fit a normal socket on the other hexagonal at the free end?
