Hi Mollers

These 'nut drivers' can be used for quite a few things from heavy steel frame assembling to large machinery maintenance and instalation, i've used similar products for bolting down large diesel engines (4000hp and up) to their bed plate foundations and connecting up large diameter propshafts. We've also used them to rotate large diesel engines also........
They are normally quite slow but incredably torquey to do up large (M20 M24 etc...nuts) saves flogging them with a spanner and hammer............

Cheers. I bought one yesterday from a sale and wasn't 100% sure what it was. It has M20 and M22 drivers with it. I notice, that in the States, they're $2700 new.

Doh....
And I was gonna offer you 50quid for it......

We are actually after one at the mo' as we need one to turn a winch used to recover a MOB boat on a commercial vessel.
If you find you have no use for it then let me know.

Is it 110 or 220?

Simon

Is there a difference between a shear wrench and an impact wrench? Makes me wonder if they're specially designed for doing up shear bolts in structural steelwork. The yanks use them more than us, they have a kind of secondary bolt head which is designed to shear off when it's done up to the correct torque.

Yeah, it uses a specialist bolt with a spline on the thread end. As you say, this holds the bolt captive and it's then sheared off when sufficient torque has been applied. Clever stuff eh? Anchor is also correct, in that it can be used as a hardcore torque driver. It turns at 15rpm, there's a lot of reduction going on in there. Mind you, it ought to have fancy guts for 2k a pop.

" there's a lot of reduction going on in there. "

Some of these have an extention bar that can be fitted to block the gun against a fixed point while it does up the nut (a bit like some torque multipliers)......otherwise if your not carefull, the nut stay's still and Mollers starts rotating around at 15rpm

75quid and i pay delivery costs??
