The Nuts And Bolts Of Thread Gaging
George Schuetz, Mahr Federal Inc.
 No pun intended, but thread gaging has always seemed a rather convoluted subject to me.  So, when I was questioned on the topic recently, I asked my friend, Lowell Johnson, a recognized authority and president of the Johnson Gage Company, to explain some of the basics and offer some tips on the process.  His advice:  Don’t trust Go/No Go thread gaging.  The reason is that this process is still widely used and, despite more than 40 years of evidence to the contrary, is so inaccurate that it will literally allow square screws to fit into round holes.  Lowell even demonstrated this in testimony before Congress.
 The simple fact of the matter is that tests that only demonstrate whether or not two parts will assemble show nothing about the quality or integrity of that assembly.  Just because they go together doesn’t mean they are going to stay together.  And, in the world of threaded fasteners and components, this can be a critical issue.  But why this is so, and why you should be using a system of instrumented dimensional gaging for screw threads, requires some explanation and an understanding of how threaded components function.
 Screw threads are so common we often take them for granted.  But in reality, they are geometrically rather complex, as you can see in Figure 1.  In addition to material and heat treatment, what gives a threaded joint its strength and integrity is the amount or percent of engagement along the flanks of the mating threads.  And because their geometry is so complex, lots of things can happen to limit this contact.  Changing the lead angle in either direction will change the pitch and result in mismatched threads.  A wobble, or “drunkenness” in the thread helix will limit contact, as will a change in diameter, roundness or taper.  Even a change in flank angle will yield a thread which assembles line, but has very little flank contact and almost/zero strength.  No matter how hard you try to tighten it, the nut will vibrate loose almost immediately.
 To understand the geometrical relationships involved and to allow process control, threads are commonly defined as having two diameters:  pitch and functional.  Functional diameter is a measure of fit, or the ability of the threaded product to be assembled.  This is the only dimension checked by Go/No Go gages.
 But as we noted, this may or may not reflect the real “dimensions” of the product, due to the nature of the helix, roundness, lead and taper.  Think of a set of gears whose teeth are meshed or butting.
 Pitch diameter, on the other hand, is a much more accurate reflection of size.  It is defined as “the diameter of an imaginary cylinder passing through the thread profile at such points as to make equal the width of the ridge and the width of the groove. “This number is significant for a couple of reasons.  One, the measured value for pitch diameter at any point along the axis of the screw thread reflects the actual amount of thread material.  This is called the Minimum Material Size.  Second, for design purposes, pitch diameter is the dimensional factor which governs the shear and tensile strength of the thread assembly.  It establishes the datum from which variations from perfect thread geometry can be referenced.

 This gets much more complicated than we have room to explain, but the important thing to remember is that in a perfect screw thread--and only in a perfect screw thread--the values for functional diameter and pitch diameter are equal.  In all other threads, differences in these two values reflect variations in taper, roundness, straightness, lead and thread angle, including helical path.  In short, they reflect a smaller percentage of flank area engagement, and hence, a reduction in the performance of the threaded assembly.  Likely problems include: galling during installation:  joint loosening (due to vibration): leakage: fatigue and relaxation: slip page: and ultimately, failure.          
 Bottom line, then, is that if you are going to accurately gage screw threads.  You need a dual instrument system that measures both functional and pitch diameters.  You need to know that both are within specified tolerances and you need to know the value of the difference between them, because it is this number which provides a basis for process control (see illustration).

Digimatic Calipers

500-752A refinement now popular is the replacement of the analog dial with an electronic digital display on which the reading is displayed as a single value. Some digital calipers can be switched between centimeters or millimeters, and inches. All provide for zeroing the display at any point along the slide, allowing the same sort of differential measurements as with the dial caliper. Digital calipers may contain some sort of "reading hold" feature, allowing the reading of dimensions even in awkward locations where the display cannot be seen. Ordinary 6-in/150-mm digital calipers are made of stainless steel, have a rated accuracy of 0.001 in (0.02 mm) and resolution of 0.0005 in (0.01 mm). The same technology is used to make longer 8-in and 12-in calipers; the accuracy for bigger measurements declines to 0.001 in (0.03 mm) for 100–200 mm and 0.0015 in (0.04 mm) for 200–300 mm.
Many Chinese-made digital calipers are inexpensive and perform reasonably well. One point worth noting is battery current when they are turned off. Many calipers do not stop drawing power when the switch is in the off position; they shut down the display but continue drawing nearly as much current. The current may be as much as 20 microamperes, which is much higher than many established brands. Sometimes calipers may not work properly when the battery voltage has dropped relatively little; silver cells, preferably selected from a datasheet to have a constant voltage for most of their life, may give a much longer usable life than alkaline button cells (e.g., SR44 instead of LR44).
Increasingly, digital calipers offer a serial data output to allow them to be interfaced with a dedicated recorder or a personal computer. The digital interface significantly decreases the time to make and record a series of measurements, and it also improves the reliability of the records. A suitable device to convert the serial data output to common computer interfaces such as RS-232, Universal Serial Bus, or wireless can be built or purchased. With such a converter, measurements can be directly entered into a spreadsheet, a statistical process control program, or similar software.
The serial digital output varies among manufacturers. Common options are
Like dial calipers, the slide of a digital caliper can usually be locked using a lever or thumb-screw.
Some digital calipers contain a capacitive linear encoder. A pattern of bars is etched directly on the printed circuit board in the slider. Under the scale of the caliper another printed circuit board also contains an etched pattern of lines. The combination of these printed circuit boards forms two variable capacitors. The two capacitances are out of phase. As the slider moves the capacitance changes in a linear fashion and in a repeating pattern. The circuitry built into the slider counts the bars as the slider moves and does a linear interpolation based on the magnitudes of the capacitors to find the precise position of the slider. Other digital calipers contain an inductive linear encoder, which allows robust performance in the presence of contamination such as coolants. Magnetic linear encoders are used in yet other digital calipers.

    About the charge function (Super Caliper)
    The minimum illumination required in the uncharged state is
    60 lux. As shown in the table ‘JIS Z 9110 Artificial Illumination
    Intensity Standard’, this Super Caliper can be used
    without problems in a normal work environment.
    The charge function allows the operator to use this
    Super Caliper without interrupting work even if the ambient illumination is temporarily insufficient.
    In the fully charged state this SuperCaliper can operate
    for approximately an hour in an environment of 50lux
    illumination (less than the minimum necessary illumination
    The time necessary for full charge differs, depending on
    the charging conditions. If this Super Caliper is left unused
    in an illumination of 500 lux (usual for manufacturing
    environments), it takes approximately one hour to
    reach full charge.
