What is UNF size?
UNF = Unified National Fine Screw Thread. The Nominal Major Diameter and Threads-per-inch (Pitch) are defined by ANSI/ASME B1. 1 and are the choices for the customary Unified screws and nuts.

Which is stronger UNC or UNF?
A 1/4 UNF thread is about 14% stronger than its UNC counterpart. Coarse threads are slightly stronger (against stripping) per length of engagement than finer threads (see thread strength section below). Coarse threads are more tolerant to slight damage or corrosion than fine threads since they have more room for error.

What does 3 8 16 UNC mean?
UNC is the American standard for coarse thread and UNF for fine thread. 3/8″ is the diameter of the bolt shank… the non threaded part that the threads are cut into. Then in 3/8″ the coarse thread is 16 threads per inch and for fine thread it is 24 threads per inch.

What kind of threads do UNF pipe fittings use?
The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job. Minimize leaks in your line— these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.
Are there parallel UNC and UNF parallel threads?
Female and Male UNC/UNF threads are both parallel The UNC/UNF flank angle is 60° Unified threads comes in three different classes: for applications where a liberal tolerance is required to permit easy assembly even with slightly nicked threads
