THREAD MEASURING WIRES

INCH AND METRIC Conform to Thread Wire Standards Deltronic Thread Wires are certifies to meet or exceed requirements of the ANSI/ASME B1.2 thread standard and ANSI/ASME B1.16M Standards.

Tolerance Commonly three wires within each set are within five millionths (.000,005"), .00013mm. of calibrated size; Set diameter is plus or minus 20 millionths (.000,020") .0005mm of "best" wire size and calibrated to the nearest 10 millionths (.000,010"), .00025mm of 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" of the wire's length is within 10 millionths (.000,010"), .00025mm maximum deviation. Thread wires are manufactured by our parent company, Deltronic.

Wire Set Packaging Each set of three 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 Certificate of Accuracy contained in each set box.

Acme Wires Best Wire Sizes are in stock for 29 degree Acme Thread Checking. Certification and tolerances match those of Deltronic's standard 60 degree thread wires. These three wire sets are packaged in the vials within labeled boxes the same as all other Deltronic thread and gear wires.
