You don't have to spend a fortune to get a great torque wrench. Torque wrenches last a couple of decades if you take care of them. I think it's one area where spending a little more is really worth it. Good tools are a pleasure to use for a long time. And as Grant Gunderson said above, small fasteners have much less tolerance for inaccuracy. Plus, a broken small bolt is a ***** to get out.
I had the CDI/Snap-on ¼", seemed accurate but the scale was hard to read. I also got tired of dealing with inch-pounds. I sold it and got a
Hazet from Amazon.de. More accurate and easy to read. Those are about $475 msrp and usually $200 to $240 at Amazon US. Oddly, the prices are way lower by buying direct from Germany. The prices on Amazon vary by -- I dunno, the phase of the moon? -- but it ranges from from $130 to $150 so just check back to get a better price. To convert the price to dollars, take off 20% because we don't pay EU sales tax, then add 10% for Euro-dollar currency conversion. Shipping is about 10 days by DHL.
Oh, and I'll warn you to resist the urge to check Amazon.de prices on other high-end German tools like Knipex or Stahlwille unless you want to feel like a 1950s housewife at a Macy's sale.
