Thread plug gauge ACME

ASME B1.5
ACME threads are a specialized screw thread type designed to provide a stronger and more durable alternative to traditional trapezoidal threads. They are specifically engineered for power and motion applications, such as lead screws in jacks, machine tool feed screws, and other mechanical motion transfer mechanisms.

The ACME thread profile is broader and more robust than standard threads, allowing for better load-bearing capacity and reduced wear. They are available in both single-start and multi-start versions, which can be used to adjust motion speed and power transmission based on application requirements.
