Props in this range have become very popular with the ‘expanding’ interest in live steam at all sizes and scales. They combine the early 20th century, narrow chord blade style, with larger pitch than our standard scale props. The pitch ratio of all the steam props is approx. 1.5:1.
The typical thread types for these props are M2 (for very small props), M3, M4 and M5. You can specify another thread type if you know exactly what you need.
Reference numbers for this range give the diameter in inches followed by the pitch in inches. Eg. 2030 is 2" dia. x 3" pitch.
