Brass Knurled Nut Internal Thread Cap Nut Solid Knurling Fasteners Supplier

Brass knurled nut is the nut made of brass with a knurled outside surface. This facilitates tightening by hand (thumb nut) or secures the nut in a substrate (insertion nut). Ever Hardware provides custom-made fasteners and customizable packaging.

Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled, or crossed lines is cut or rolled into the material. The operation is performed for producing indentations on a part of a workpiece. Knurling allows hands or fingers to get a better grip on the knurled object than would be provided by the originally smooth metal surface. Occasionally, the knurled pattern is a series of straight ridges or a helix of “straight” ridges rather than the more-usual criss-cross pattern.
Knurling may also be used as a repair method: because a rolled-in knurled surface has raised-up areas surrounding the depressed areas, these raised areas can make up for wear on the part. In the days when labor was cheap and parts expensive, this repair method was feasible on pistons of internal combustion engines, where the skirt of a worn piston was expanded back to the nominal size using a knurling process. As auto parts have become less expensive, knurling has become less prevalent than it once was, and is specifically discouraged by performance engine builders.
Brass is a metal alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.
