Thread Measuring Wires

Meet or exceed requirements of the ANSI/ASME B89.1.17, B1.2, B1.16, B1.5, B1.8 thread standard
as well as Federal Spec. GGG-W-366b and ISO Standard.

Standard Thread Wires

Thread Measuring 3-Wire Sets

Each set of 3 wires is contained in a screw-top vial. The vial is packaged in a hinged-lid box which is labeled to show pitch and Calibrated Wire Size. The Calibrated Wire Size is also shown on the Certification of Accuracy contained in each set box.

Commonality, three wires within each set are within 5 millionths (.000,005”), .00031mm of calibrated size;

Set Diameter is within 20 millionths (.000,020”), .0005mm of “best” wire size and calibrated to the nearest 10 millionths (.000,010”), .00025mm of the exact size.

Roundness is within 10 millionths (.000,010”), .00025mm.

Surface Finish is better than 2 microinches AA, lapped.

Hardness, Rc 62-64 stabilized.

Straightness of the central 1/2 inch of the wire’s length is within 10 millionths (.000,010”), .00025mm maximum deviation.

Master Libraries

All Thread Wire Libraries are available as “Master Libraries” (i.e., used to calibrate “working” wire sets by simple comparison techniques). Master Libraries include only one wire per pitch, calibrated to the sixth (one millionth) decimal place and including traceability — NIST test number. Master Thread Wire Libraries include Gage-Carry Cases.
