Cabinet assembly screws wood furniture board connecting bolts

Cabinet assembly screws are pan-head Phillips drive knurling shoulder double wood tapping threaded screws. Also used on furniture board connecting. Ever Hardware provides custom made cabinet assembly screws 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.
Knurling can also be used when a component will be assembled into a low precision component, for example, a metal pin into a plastic molding. The outer surface of the metal pin is knurled so that the raised detail ‘bites’ into the plastic irrespective of whether the size of the hole in the plastic closely matches the diameter of the pin.
