Thread types on threaded fasteners

Threads on both metric and UTS fasteners are also categorized as coarse, fine, or extra-fine. UTS thread types are typically labeled UNC (Unified Coarse), UNF (Unified Fine), or (Unified Extra Fine (UNEF). There is no difference in manufacturing quality between coarse, fine, and extra-fine thread types, but there are differences in how they are employed.
Coarse threads are thicker and more durable than fine-threaded hardware. Coarse-threaded fasteners can also be installed more quickly. For instance, a 3/4-10 UNC requires 10 rotations to install 1 inch of the bolt shaft, while a 3/4-16 UNF would require 16 rotations.
Fine and extra-fine threads can be examined together. Their smaller pitches and greater TPI equate to better tensile strength, and a larger minor diameter provides better shear strength. Smaller thread helix angles also provide superior resistance to vibration in fine-threaded fasteners, a very important consideration.
