Kasey, check every bolt and write down the torque it takes to make the stretch you want. I try and hit the middle of the stretch, IE if it says .0056 to .0062 I shoot for the middle .0059  if the bolts are new follow the rod bolt makers suggestion on the initial use  Also if they are new write down the free length before stretching them

what is the guaranteed parallelism from point to point?

Some of the best shops in the world have these gauges sitting on the shelf. They got them, used them, tested them against what they had been doing for years and then the tool found its way to the back of the tool closet. They are like trans temp gauges--you get one--run a few races , then see what happens when and how--then you don't need one again. They are a good test to see what is really happening when you torque bolts the way that you always do but if you have a good torque wrench that is calibrated for the numbers you use and you always do it the same way with the same lube etc--I don't think you will ever fail a bolt or rod because you did not have a gauge---we have the tool to check our wrenches and the technique of the user ALWAYS makes more diff than the calibration which is never far off. A $50 Sears or Lowes wrench can often be as good as a $400 Snap On or Mac based on our test. An experienced engine builder can tell when a rod bolt does not feel right during the tightening procedure--the you discard it, replace it, check and touch up the rod and keep going---The LACK of quality we put up with on ALL brands of bolts is the trouble--you get a softie every now and then so a gauge will not tell an inexperienced user that the bolt is no good. So..IMO back yard twice a year builders just save your $$. OK...let the poo fly.

Mine made it to the back of the tool box before I ever used it. I bought it before I realized my C&A rods have a blind hole.

They're drilled & tapped in a fixture and each one is tested after assembly. You'd have to have ridiculous deflection, say .250, to affect the measurement by .001, basically impossible.
i was just asking a simple question. i've seen some stretch guages that are not parralel from end to end. that causes big problems with repeatability.
so back to your remark; if you had even .005 of deflection, the guage would be worthless. a lot of things are made in fixtures, that doesn't meen they're made right, or are accurate. your guages are probably just fine but i felt the need to express my thoughts after your .250 deflection remark.
and for the guys that toss them in the box and don't use them any more, stop being so lazy and do it right.
