Assorted Industrial Hardware and Machine Components

This item is a collection of various metal hardware and industrial components, stored haphazardly in an open cardboard box. The primary visible piece is a large, circular, flat metal disc, appearing to be made of aluminum or a similar light-colored alloy. It features numerous drilled holes of varying sizes, arranged in an irregular pattern, suggesting it may be a mounting plate, a part of a machinery assembly, or a specialized flange. The surface of this disc shows signs of use, including scratches and scuff marks, indicating it is not new. Other visible components include several smaller, dark-colored metal washers or discs, multiple screws and bolts of different dimensions, and two more substantial metal pieces. One of these larger pieces is a hexagonal-shaped nut or coupling made of a darker, possibly steel, material, showing some surface wear. The other is a cylindrical metal part with a hollow interior and a protruding connecting element, also appearing to be steel or a heavy alloy. The overall condition of the contents suggests they are used, surplus, or salvaged parts from machinery or industrial equipment. There are no obvious maker's marks or identifying signatures visible in the image. The style and construction appear functional and utilitarian, consistent with industrial or mechanical components, likely from the mid to late 20th century or possibly more recent, given the lack of significant rust or heavy patina on most pieces. The craftsmanship appears to be standard for machined metal parts, focusing on functionality rather than aesthetic appeal.
