Thread Standards Tameson com

The unified thread standard has three distinct variances called Unified Coarse Thread UNC Unified Fine Thread UNF and Unified Extra Fine Thread UNEF The difference between the three is the amount of threads per inch For example a 1 inch fastener size in UNC has 8 TPI in UNF 12 TPI and 20 TPI in UNEF

Determining Your Lathe Spindle Thread to find the correct

Ensure that the thread on the adapter and lathe spindle has the exact same pitch and standard Even if the thread size is the same there are different standards of threads e g UNC UNF and BSW If mismatching standard threads are used it may cause damage to both lathe and chuck therefore you will have to know the thread of the spindle accurately
