Park Tool TW-5 Torque Wrench

Product Information

Below is a table of torque equivalents and formulas for conversions follow the torque table. The table is also available as a PDF file. Even with such praise, it’s priced at a premium and doesn’t offer a great deal over more generic Taiwanese options. It’s certainly one for those who appreciate both form and function. The torque setting is set by twisting the bottom of the handle and watching the little red indicator move to the desired number. Those numbers are only even, so there’s an element of estimation for odd numbers – and many bolts require 5Nm. For all its good looks, high quality appearance and premium price tag, I was slightly disappointed with the wobbly feel when using the tool.

The TW-1.2 has a range of 0–14 Nm (0–140 inch-pounds). The TW-2.2 has a range of 0–60 Nm (0–50 foot-pounds).

TW-1 Features

With the parts slotted together, you can feel the join between them, given away by a movement that I feel wouldn’t be there if each part was more precisely sized to slot together more snuggly. Firstly, make sure you are holding the tool properly. If you are holding the tool by the head or in the middle, you are putting more torque through the bolt than you are intending. You should hold the torque wrench by the grip.

Effetto’s Mariposa Giustaforza II 2-16 Pro Deluxe torque wrench is a high-quality option. David Rome / Immediate Media This tool offers everything we loved about the Park Tool PTD, but with further adjustment options. Accuracy is not quite as consistent as the preset options, but certainly close enough. Its American-made build quality is superb, but that does mean it’s heavy and priced relatively high. Torque wrenches are calibrated in Nm (Newton-metres, which is a unit of torque of momentum) but you’ll also see Ft/lb or In/lbs. One is metric and the other is imperial. Fasteners often have both values written next to them. Can I use it incorrectly?It works like a beam-type torque wrench and so you stop tightening once the needle hits the desired number.
