This 3-wire holder thread wire set offers a fast and accurate method for measuring thread plug gages. It effectively monitors wear and controls pitch diameter variation during thread fabrication, significantly reducing measurement time. Compatible with micrometers having a 0.250 in anvil/spindle diameter, this set helps ensure precise thread size control by detecting out-of-roundness and taper. It is suitable for both pre-plating and post-plating applications, ensuring quality control to demanding specifications. Includes accuracy certification and is traceable to NIST, meeting or exceeding all ANSI and ISO standards.
