UNF Hex Machine Screw Nuts ASME B18.2.2 in A2 Stainless Steel
Hexagon Machine Screw Nuts (UNF - Unified Fine Pitch) imported from the USA. These nuts generally have
smaller internal diameters than the range available in standard hexagon nuts, so fit the smaller gauge
sizes for Imperial screws. They also tend to be thinner or lower in height but have a larger outer diameter.
These are specifically designed to be used in conjunction with other UNF screws or bolts. Often used
in small electrical goods manufacturing, such as computers and hifi systems.
