CALIBRATION CERTIFICATES

Certificates (where these are required) are carried out by a certified calibration lab.

FMS calibration plates do not normally require recertification as there is virtually no wear from calibration. Probably the only time necessary is if the plate is dropped or mishandled.

FMS are specialists in measuring the pitch diameter (and external minor diameter d1 plus internal major diameter D if required) of virtually all thread type and diameters. There is money to be saved if you usually buy and use thread plug and ring gauges especially for non-standard and unusual thread types.

As a customer all reasonable practical thread questions re type and tolerances will be answered.

N.B. We do not sell thread ring and/or plug gauges.

Measuring internal threads requires a refence.
A calibration plate is such a reference and almost always give a measurement accuracy of ± 0.01mm/0.0005”

ADVANTAGES WHEN USING FMS

Know where you are within the tolerance.

Measure at the machine and when setting up.

The only limit to measurable diameter is caliper length.

With FMS thread inserts 1 pair of inserts with numbers 21, 22 and 23 can replace at least 4 sets of thread wires or balls.

A FMS calibration plate is not necessary for measuring external pitch diameter (d2) but can calibrate measurement and caliper accuracy. 20.00mm is the standard for d2 and 50.00mm for D2 unless otherwise specified or ordered. A calibration plate is necessary for internal pitch diameter measurement.

FMS thread inserts type 21B and calibration
plate 30A.
d2= 20.00mm
D2 = 50.00mm

Zero (0.00mm) and then measure d2 on the calibration plate. The result should show 20.00 ±0.01. The measurement result on a thread will be the actual pitch diameter after zeroing..

Thread inserts type 22B for internal thread pitch diameter measurement. Zero (0.00mm) the caliper and add 50.00mm to the measurement result for actual pitch diameter.

Thread inserts type 22B for internal thread pitch Thread inserts type 23B for internal thread pitch diameter measurement. Zero (0.00mm) the caliper and add 50.00mm to the measurement result for actual pitch diameter.
