Roll Pin Kit Appraisal

Assorted Dowel/Roll Pin Kit

This item is a commercially available assortment kit containing various sizes of what appear to be dowel pins or possibly roll pins, housed within a clear plastic compartmentalized storage case. The pins themselves are uniformly black, suggesting a material like hardened steel with a black oxide finish for corrosion resistance, common for industrial or mechanical applications. The kit includes a wide range of lengths and diameters, organized into multiple rectangular compartments within the clear case. On the right side of the case's lid, there is a printed or adhered label providing specifications for the different pin types, including their dimensions (e.g., 'Ø: 10 mm' and varying lengths denoted as 'L:'). Some sections of these labels show minor discoloration or smudging, indicative of use or age. The pins are generally cylindrical, with some appearing to be solid dowel pins and others possibly slotted roll pins based on the slight visible seams on some examples. The overall condition of the pins appears good, with no obvious signs of rust or significant wear; however, some of the very smallest pins are in small plastic bags within their compartments, presumably to keep them together. The clear plastic case shows typical signs of handling, such as minor scuffs and surface dirt, but no apparent cracks or major structural damage. The compartmentalization is a key feature, allowing for organized storage and easy identification of different pin sizes. This type of kit is commonly used in machinery assembly, repair, and prototyping, where precise alignment and joining of components are required. The craftsmanship seems standard for manufactured hardware items, focusing on dimensional accuracy and utility rather than decorative appeal. The style period is contemporary, as these types of organizational kits and standardized fasteners have been in common use for many decades.
