What is the CDI 2503MFRPH torque wrench?
ThisCDI torsion wrenchmeasures torque in imperial social unit ( 30 to 250 foot - pounds ) and metric unit ( 47 to 332 Newton meters ) . It features an easy - to - adapt collar for choose the hope torque . However , I found myself wish it had stamped measurements rather than optical maser - etch etching , as the latter can be hard to see if they get greasy or if the kindling is misfortunate .
It appraise 24.4 inch long , with a head that is 1.7 inches wide-cut and 1.4 inches deep . It weighs 3.2 pounds and has a cushiony comfort grip , although I feel the handgrip more or less minor . Someone with larger hired man might prefer touse a torsion wrenchwith a bigger grip .
The ½-inch drive torque spanner has a quick - liberation release for change socket apace , and it comes in a intemperate storage example to safely stash away the tool . The only downside is that the grammatical case is somewhat short . When torque wrench are not in habit , manufacturers typically recommend relinquish the tensity , but when I to the full undo the tautness , the prick was a hair too longsighted to well fit in the compositor’s case . I had to tighten it a twist or two so that it would go . This was n’t a large tidy sum , but I would have preferred the guinea pig to be long enough to store the cock without any tension on the innerspring .

Accuracy
The CDI comes precalibrated with an truth of ±4 per centum clockwise ( CW ) and ±6 percent counterclockwise ( CCW ) . I did a simple comparative test for accuracy by setting the CDI and another torque wrench , theDeWalt DWMT17060 , to 100 foot - pounding and then using them on the same fastener to see if there were any celebrated discrepancy . There were n’t any disparities , although it was n’t an apples - to - apples equivalence because the DeWalt is adigital torsion wrench . Still , both torsion wrenches register the same tension on the fastener . On top of that , the CDI comes with a credentials of standardization second by theNIST .
Drive Size, Range, and Usability
The CDI ’s ½-inch parkway and 30- to 250 - groundwork - pound range make it various for medium - to heavy - duty fastening applications . Its 2 - foot length offers plenty of leveraging for tightening high - torsion Nut . Still , it also make the putz a picayune clumsy if you ’re using it for lower - torque applications , such as tightening addict on , say , a lawn mower or bike .
TheCDI torsion wrenchwas just right for tightening the lugs on my cable car , but it was too cumbersome ( and did n’t set gloomy enough ) to tighten several nuts on my husband ’s Harley . My husband assisted when testing the CDI on higher - torsion fixing on our skid steer and tractor because those fasteners require more physical strength to constrain .
This is a ready to hand torque pull for many car and machinery app program . Its ½-inch drive deal large ½-inch socket , but you ’ll ask to bind a reducer to employ it on smaller sockets . If you ’ll be working with pocket-sized , lower - torque holdfast , you may detect it unsubdivided to habituate a smaller choice , such as theCapri Tools 31200torque wrench .
