I need a torque wrench capable of accurately torque a nut to 500lbs. Any recommendations on brands or stores? I am on a tight budget.

 

I've never seen one go that high.The most was 300 ft lbs.If there is one capable of 500 ft lbs,I bet it's going to be pricey.
Try Snap-on?

 

Harbor Freight Tools - Quality Tools at the Lowest Prices

Looks like the cheapest price around. Snap On sells a 3/4" drive that goes to 600 and that's about $800. I don't think you'll find a 1/2" drive that goes that high.

 

Thanks I'll look at Harbor Freight.

 

You don't need a complete torque wrench. If you allready have a good one, all you need is a "Torque Multiplier".............

 

Hmmm torque multiplier....I just love the thought of new tools.

 

It might be expensive, never bought one, but have used a handfull.
Doubt that it would be found at a discount tool place like harbour freight. But I've been wrong onr other time.

They have one a little less expensive than this, but it is too new in their line-up for reviews.
This was was reviewed favorably (as long as you believe the reviews are truthful!)

Yup to go that high in just one wrench, you will need a 3/4" torque wrench. big beefy b@$tards.

 

I have that one for the lug nuts on my '52 F-4 truck. It's a beast, but cheap.

Thanks for the suggestions. I am going to be adding a tool or two to my toolbox.

 

you can build your own torque multiplier, see page 2 of this link http://www.motionpro.com/images/documents/08-0134.pdf the more final torque you need the longer adapter you use.
I have one for the fan nut on Robinson helicopters that is about 3 or 4 foot long, 1/2" X 1 1/2' bar stock. I welded a 3/4 inch male square drive that I cut off of an extension on one end and a 1/2 inch female square drive off of a 1/2 inch extension on the other end. I than stamped the formula on the bar so I didn't have to look it up every time I used it.

 

You can pick up Pronto (Stanley) or K&D 3/4" torque wrench on EBay at pretty good prices. Seen them going for new or slightly used for around $200-$300.

 

Just a suggestion I have a snapon that goes to 600 # but if you only need it once in awhile have you thought about renting.

 

Our Snap On at work goes to 600 but it cost about $800.
