JBO Thread Gaging Solutions
JBO Thread Gaging Solutions
Features of JBO Thread Gages
Excellent wear behavior due to supreme surface finish of thread flanks and high hardness ≥ 62 HRC for long gage life.
Gages are produced to the reduced tolerance wherever permitted by the overall gage tolerance.
Large stocks covering more than 10,000 different thread dimensions and tolerances for quick delivery.
Metric thread gages manufactured to DIN ISO 1502 / UN thread gages manufactured to ANSI / ASME B1.2

Advantages of using a MultiCheck
- One single thread depth gage for checking both – accuracy to thread size and thread depth
- Thread gauging cycle time reduced by 50% (eMC 80%)
- Thread depth up to 4xD can be measured (eMC up to 50 mm)
- Application of standard thread plug gages slightly modified
- Simple replacement of worn plug gages
- Reliable reading of the thread depth from measuring sleeve or digital readout
- Coated version on request
If you wish to replace a worn thread plug gage that is no longer within the specified tolerance yourself, you need a dismantling kit consisting of a draw-off nut, a long spacing sleeve for the “GO“ end and a short spacing sleeve for the “NOT GO“ end.
The MultiCheck measures the length of fully formed thread. This is not exactly identical with the depth to which a screw can be screwed in, due to the distance of the start of the thread from the workpiece face.
The distance from the face to the first complete thread is 0.5 x pitch ± 0.02 mm. This ensures precise calibration with our setting gauge.

Operating mode
With an eMultiCheck, testing is initiated automatically via a short press of a button. The electronics recognizes the thread and begins the testing procedure by screwing in the GO thread plug gage according to a defined torque. This occurs without the tiresome manual screwing in of the thread plug gage’s GO side. The GO thread plug gage is traversed out of the workpiece again by pressing the second push button.
