Thread Height InspectionDescriptionModels☟PointsVideosMeasuring thread height helps monitor and control the depth of cut during manufacturing, detects broken inserts, and can be used to calculate the minor or major diameter, when only one is known.Accurate thread height contributes to the interchangeability and integrity of the threaded assembly.For inspecting your straight thread heights, Gagemaker recommends our TH-3001V (external) and TH-3010 (internal) .

Measuring thread height helps monitor and control the depth of cut during manufacturing, detects broken inserts, and can be used to calculate the minor or major diameter, when only one is known.

Check proper form and pitch by placing the correct profile template into the threads. By shining a light behind the profile template, it’s possible to detect any steps or signs of a chipped insert. A template that stands too far out of the threads or allows excess light to shine through can be an indication of lead error. Sweeping the profile template along the helix of the threads helps find burrs or debris.

Lead error is most commonly generated by manual and CNC lathes not cutting properly. Therefore, it’s important to take measurements at the locations where the most lead error typically occurs. These readings help detect machine tool error and worn lead screws on your lathe.

Gagemaker also manufactures functional inspection gages that inspect internal GO/NO GO thread diameters. Software, gages, and thread rolls are sold separately. For gages with ranges greater than 16”, please see our functional size product page. Higher resolution indicators are also available.

Other features of the program include the ability to print thread dimension reports, providing a paper copy of any calculation. These reports provide the same critical dimensions that display in the program. A multiple calculation window capability is a feature that allows performing several different thread calculation at the same time.

Gagemaker pitch diameter gages, commonly known as ball PD gages, verify that your part is within allowable tolerances. Improperly sized pitch diameters compromise the load capacity of your threaded components. The ball pitch diameter gages gages indicate the pitch diameter size of the product’s external and internal threads. The gages are adjustable within a size range and use interchangeable contact points to measure different pitch threads. Setting dimensions for the pitch diameter gages are provided by the TDWIN™ Thread Disk software.

The LG-5003 uses the three-point system to inspect internal and external thread lead. Two fixed contact points at the rear of the gage and one movable contact point at the front of the gage provide complete stability when taking thread lead measurements. This unique design does not require sweeping to obtain measurements.

Insert IdentificationDescriptionModels☟The first step in the quality process is to ensure the threading insert being used is correct for the job.Use the JSS™ Thread Insert Identifier Template to quickly verify that the correct threading insert has been selected as well as check the full topping profile of both internal and external inserts.A quick mating of the insert to the template ensures the insert is correct for the job.JSS™ insert identifiers have multiple notches on each template and are available for all ANSU thread forms.Gagemaker’s straights thread insert identifiers easily determine which threading insert the machinist is using.When an optical comparator is unavailable, the insert identifier will show which thread form is on the insert.Internal ACME & Stub Acme Insert Identifiers Thread TypeThread FormTaper per Foot/PitchModel StraightInternal ACME3P, 3.5P, 4P, 5P, 6P, 8P, 10P, 12P, 14P, & 16PTI-ACME-INT StraightInternal Stub ACME3P, 3.5P, 4P, 5P, 6P, 8P, 10P, 12P, 14P, & 16PTI-SACME-INT

Lead GagesThe LG-6001 and the LG-6002 use a two-point system to inspect thread lead for straight and tapered threads. The LG-6002 inspects both external and internal threads, while the LG-6001 inspects external threads. The two point system allows for a sweeping action to obtain the measurement. Both gages are available with higher resolution indicators.The LG-5003 uses the three-point system to inspect internal and external thread lead. Two fixed contact points at the rear of the gage and one movable contact point at the front of the gage provide complete stability when taking thread lead measurements. This unique design does not require sweeping to obtain measurements.Contact points can be easily changed to allow the gage to be used on a variety of thread forms. Each gage comes with one set of contact points.Before inspecting parts, the lead gage must be preset to a nominal predetermined dimension using a lead gage setting standard. Lead standards are available for both straight and tapered threads. Our setting standards are manufactured according to ANSI and API specifications, respectively.

Thread Form InspectionDescriptionModels☟VideosCheck proper form and pitch by placing the correct profile template into the threads. By shining a light behind the profile template, it’s possible to detect any steps or signs of a chipped insert. A template that stands too far out of the threads or allows excess light to shine through can be an indication of lead error. Sweeping the profile template along the helix of the threads helps find burrs or debris.Thread FormGagemaker manufactures precision straight thread profile gages for the quick identification of product thread forms.

Functional gauging takes into account the cumulative effects of diameter, lead, taper, flank angle and form error. Experience the same functionality of ring and plugs with the added benefit of accurately inspecting a range of sizes.

Gagemaker develops and manufactures precision mechanical inspection equipment for the Oilfield, Mining, Water Well, and General Machining industries. Gagemaker products are used in countless facilities around the world. Gagemaker's commitment to actively developing new products along with their superb customer service has set the industry standard for almost 40 years.

Gagemaker’s JSS® Thread Inspection System for ACME, ANSI & ISO Metric. Today’s dynamic manufacturing environment overwhelms old “GO/NO GO” methods and only our Straight Thread Inspection System consistently goes above and beyond. An effective Straight Thread Inspection System should measure all of the vital thread attributes – Functional Thread Size, Pitch Diameter, Thread Lead, Thread Height, and Thread Form.

Experience the same functionality of ring and plugs with the added benefit of accurately inspecting a range of sizes.Functional thread inspection gages, or GO/NO GO gages, measure thread diameters. These functional gages are adjustable within a size range and use interchangeable thread rolls to measure different pitch threads.Setting dimensions for the functional pitch diameter gages are provided by the TDWIN Thread Disk™ software.

Contact points can be easily changed to allow the gage to be used on a variety of thread forms. Each gage comes with one set of contact points.

The Thread Disk™ engineering software (TDWin™) calculates critical dimensions for threads based on ANSI tables and formulas. Thread types supported by the program include: UN, UNJ and UNR Series, Acme, Stub Acme, Stub Acme Modified I and II, Metric M & MJ, 7° X 45° Buttress, and General Purpose Pipe Threads.

The first step in the quality process is to ensure the threading insert being used is correct for the job.Use the JSS™ Thread Insert Identifier Template to quickly verify that the correct threading insert has been selected as well as check the full topping profile of both internal and external inserts.A quick mating of the insert to the template ensures the insert is correct for the job.JSS™ insert identifiers have multiple notches on each template and are available for all ANSU thread forms.

Functional thread inspection gages, or GO/NO GO gages, measure thread diameters. These functional gages are adjustable within a size range and use interchangeable thread rolls to measure different pitch threads.

If measuring internal and external shallow taper diameters is a problem, the Ball mic SET DIM Tool provides setting dimensions for ball micrometers or Gagemaker’s BX-1000 groove gage. The program calculates ball mic settings for any tapered surface geometry.
