The Norbar Torque Wrench Extension Calculator for iPhone from www.ifreeware.net

Measure from center of handle to center of drive. With a 6 extension, parallel to a torque wrench with 12 between the handle pin and the center of the drive square, the torque value set on your clicker wrench should be reduced by 1/3, the same ratio of the extension over the standard wrench. Most commonly you will want to know what setting to use on a torque wrench to get some specific torque when using an extension.

The torque you wish to apply is found by dividing l into the sum of l + e and then using the result as a correction factor. In order to get an accurate reading from a torque wrench, you must always place your hand in the correct spot, maintain the torque wrench parallel to the fastener at all times, and avoid any wobble or universal (swivel) sockets.

That is if they’re used properly, and you’re using your torque wrench correctly. In order to get an accurate reading from a torque wrench, you must always place your hand in the correct spot, maintain the torque wrench parallel to the fastener at all times, and avoid any wobble or universal (swivel) sockets.

The Short Answer Is No, Extensions Do Not Affect Torque Wrench Accuracy.

The following formula is used to calculate the torque setting of an extended wrench. F = y / l and f = t / ( l + e ) f = f therefore substituting we get: When you put an extension on a torque wrench (e.g.

Measure From Center Of Torque Wrench Adapter Drive To Center Of Tool Extension Adapter, This Is = E.

M1 = m2 x l1 / l2….torque wrench extension formula. T1 = t2 * (l1/l2) where t1 is the torque setting of the wrench. Any extension can be compensated for with a simple calculation.

Adapters Or Extensions Should Only Be Used In Line With The Wrench, As Opposed To Being At An Angle, And The Actual Torque Applied Will Be Greater Than The Torque Reading Shown.

And they are mixing up the terms. L1 is the normal length. Still unable to zip it off.

If You Turn One Side Of The Bar, The Other End Must Have An Equal Affect On The Other End.

Measure from center of handle to center of drive. Determine desired torque applied to fastener or whatever, this is equal to t. On the other side, i was able to get with a wrench and cheater bar.

Socket Extensions Do Not Affect The Accuracy Of A Torque Wrench.

If configured to apply the same torque to the extension, it makes no sense that the resultant torque would be different. T = f · ( l + e ) rearrange for f: Equation for torque wrench adapter:
