What is UNF in thread size?
Unified form thread designations are represented by abbreviations such as UNC (unified coarse), UNF (unified fine), UNEF (unified extra fine), UNS (unified special) and UN (unified constant pitch), with the thread major diameter preceding the designation for example, 9/16” UNC, 9/16” UNF.
What is a 1/2 thread pitch?

What is UNF thread type?
UNF stands for ‘Unified Fine’, which is also a popular thread in the United States. UNF fixings are often used in the automotive and aerospace industries industry because of the requirement for tight, fine threads. UNF fasteners are typically made from steel or stainless steel fasteners.
