The Moore & Wright MW800 Series Screw Pitch Gauges are precision thread identification tools designed for accurately checking both internal and external thread forms. Manufactured with accurately milled steel blades and housed within a robust steel sleeve, these gauges provide a reliable solution for engineers, machinists, toolmakers and maintenance professionals working with a variety of thread standards.
Each blade is clearly marked with its nominal thread size for quick identification, whilst the folding design allows convenient storage and easy blade selection. The range includes S.I. Metric, ISO Metric, Whitworth, Unified and American National thread forms, making the MW800 Series suitable for a wide range of workshop, inspection and maintenance applications.
All gauges are manufactured using durable steel blades for long service life. Selected models include a screw cutting gauge to assist with thread form verification and identification. These gauges provide a simple and effective method of determining thread pitch during manufacturing, inspection and repair operations.
