Alameda NS-2B GO PD.9014 NO GO PD.9063,SB Go Thread and Plug Gauge

Alameda NS-2B Go/No-Go thread plug gauge for 15/16-18 threads (SB designation) provides a Go pitch diameter of 0.9014 in and a No-Go pitch diameter of 0.9063 in. This precision tool is used to verify internal threads by comparing the plug gauge against the hole: the Go PD should fully engage the thread, while the No-Go PD should not pass through, indicating the thread is within the NS-2B tolerance class. Being a 2B-class Alameda gauge, it targets standard internal-thread inspection practices in metalworking and manufacturing environments, where quick, decisive go/no-go checks help ensure proper thread fit and component interchangeability. The specified PD measurements define the allowable tolerance window for the 15/16-18 thread family, and the values are expressed in inches to align with common imperial-thread gauges. This gauge can be paired with other NS-2B or related Alameda gages on the same inspection station to streamline quality control and reduce guesswork when validating tapped holes intended for mating fasteners of this size.
