Full Nuts - UNC Left Hand
The name full nut refers to a standard hexagon nut. They are the most common type of nut and are available in a wide variety of sizes, grades, finishes and thread types.
UNC stands for Unified National Coarse. It is a common imperial thread type with less threads per axial distance than its UNF equivalent.
Unified thread types (UNF and UNC) were introduced at the beginning of World War 2 to enable the interchangeability of machinery manufacturing between the USA, Canada and Great Britain. Still commonly found on a vast array of old machines and vehicles in the UK, UNF and UNC threads continue to be the standard thread in the USA and Canada.
The UNC left hand tightens and loosens in the opposite way to the standard UNC nut.
