Automotive Wheel Weight Appraisal

Zink-Plated Wheel Weight

This item is a small, rectangular metallic component identified as a 3-gram wheel weight, commonly used in automotive applications for dynamic tire and wheel balancing. Measuring approximately 10mm to 15mm in length, the piece is constructed from steel and finished with a yellow zinc-plated coating to provide corrosion resistance. Centrally embossed on the obverse face is the alphanumeric marking '3GM', indicating its precise mass. The object features rounded corners and a low-profile, flat-top design, which is characteristic of adhesive-type weights found in modern vehicle wheel assemblies. Its surface exhibits a dull, iridescent golden-yellow sheen typical of trivalent or hexavalent yellow chromate plating over zinc. Regarding condition, the metal shows minor surface scuffs and slight darkening in the recesses of the lettering, suggesting exposure to industrial environments or light handling, though no significant oxidation or structural deformities are visible. The craftsmanship is utilitarian, produced via high-speed stamping and plating processes typical of contemporary automotive hardware manufacturing.
