Machine Screws - Pozidrive Countersunk - UNC

A machine screw is a type of screw that is commonly used in industrial and manufacturing applications to secure components within engines, electronic products and general machinery.

Countersunk machine screws are designed for installation in countersunk holes to enable them to sit flush within the finished surface. This type of fastener should be installed with a pozidrive screwdriver or bit.

They are available in either a zinc plated or stainless-steel finish.

About UNC Thread

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.
