Go thread plug gauge
  • The go thread plug gauge checks the so-called "mating size" of the internal thread and the screwing-in capability. In doing so, it checks the smallest size of the internal thread pitch diameter D2 including certain form deviations in the thread, e.g. pitch and thread profile angle deviations. It also checks the smallest size of the major diameter. The minor diameter D1 of the internal thread is not checked.
  • The go thread plug gauge must be able to be screwed by hand into the full length of the workpiece thread without using particular force. The permissible wear of the go thread plug gauge is determined by measurement based on the three-wire-method. The go thread plug gauge is subject to heavy wear and should be checked at regular intervals. REIME therefore recommends using go thread plug gauges in the hard-chrome-plated or TiN-coated version.
  • Dimensions of the go thread plug gauge acc. DIN 2281 and DIN 2282.
  • The go thread plug gauge has a full thread profile along its thread length. It should be noted that the thread length is not less than 80% of the screw-in length of the workpiece thread. Go thread plug gauges, starting from a thread diameter of 5.5 mm, are provided by REIME with a dirt flute.
  • According to DIN ISO 1502, no so-called "acceptance" go plug gauges are standardized.
  • It is advisable to always use the new plug gauges for production and keep those that are close to the wear limit for acceptance.

No-go thread plug gauge
  • The no-go thread plug gauge checks whether the actual pitch diameter of the workpiece internal thread exceeds the prescribed largest size. The internal thread major diameter and internal thread minor diameter are not checked.
  • It must not be possible to screw the no-go thread plug gauge into the workpiece thread by hand for more than two revolutions (from both sides) without the use of particular force. The two revolutions are determined on screwing out the plug gauge.
  • The no-go thread plug gauge has a thread length of at least three threads. The thread profile has a truncated crest.
  • The gauges are marked with a red coloured ring.
  • Dimensions acc. DIN 2283 and DIN 2284.

Go/no-go thread plug gauge
  • The go/no-go thread plug gauge is the combination of a go thread plug gauge and a no-go thread plug gauge on one handle.
  • The dimensions of the go/no-go thread plug gauges are specified up to a nominal dimension diameter of 40 mm in DIN 2280. The functionality corresponds to the go and no-go thread plug gauges previously described.

Go thread ring gauge
  • The go thread ring gauge checks the so-called "mating size" of the external thread and the screwing-on capability. In doing so, it checks the largest dimension of the external thread pitch diameter d2 including certain form deviations in the thread, e.g. pitch and thread profile angle deviations. It also checks whether the straight flank piece is long enough, i.e. that the curve on the external thread root does not extend too far into the profile flank. The root curve itself is not checked. The major diameter is also not checked by this gauge.
  • It must be possible to screw on the go thread ring gauge by hand along the full length of the workpiece thread without the use of particular force.
  • The go thread ring gauge is subject to greater wear and should be checked at regular intervals with the wear check plug gauge.
  • It should be noted that the thread length is not less than 80% of the thread engagement length of the workpiece thread.
  • Dimensions of the go thread ring gauges acc. DIN 2285.
  • Go thread ring gauges in the standard version are made without dirt flute (external threads are easier to clean than internal threads prior to gauging).

No-go thread ring gauge
  • The no-go thread ring gauge is designed to check whether the actual pitch diameter of the workpiece external thread falls below the prescribed smallest size. The external thread major and minor diameter are not tested here.
  • It must not be possible to screw the no-go thread ring gauge onto the workpiece thread (from both sides) by hand for more than two threads without the use of particular force. The two revolutions are determined on screwing off the ring gauge.
  • The no-go thread ring gauge must be monitored regularly with the wear check plug gauge.
  • The no-go thread ring gauge has a thread length of at least three threads. The thread profile has a truncated crest.
  • The ring gauges have a red marking.
  • Dimensions acc. DIN 2299.

MMT thread depth plug gauges
The MMT go/no-go thread depth plug gauge permits the gauging of threads and the measuring of thread depth in one single work process. The typical application for the MMT thread depth plug gauge is in components with identical thread sizes and different thread depths, and in the setting of thread depth in all kinds of internal thread production. By pushing the spring-loaded scaled sleeve into the handle, the fully cut thread depth can be read off quickly and precisely. In addition, the MMT plug gauge will of course meet all the specified requirements and gauging criteria as specified in DIN ISO 1502 for standard go/no-go thread plug gauges.

  • Simple and safe handling – reduces inspection work by 50%
  • Available in six sizes from M2 to M24
  • Measurable thread depth up to 4 x D
  • Easy to adjust
  • Universally applicable due to exchangeable gauge bodies
  • TiN-coated gauge bodies available upon request
  • Measuring accuracy 0.5 mm
  • Optionally available with locking screw
