Type
Hardware / Fastener Component (Flat Washer)
Maker
Unspecified mass-produced hardware manufacturer
Material
Base metal with metallic plating (likely zinc-plated steel, stainless steel, or nickel-plated steel); no precious silver content observed.
Dimensions
Estimated outer diameter approx. 15-20 mm, inner hole diameter approx. 6-8 mm, thickness approx. 1-1.5 mm; weight under 5 grams.
Description
This object is a standard industrial flat metal washer rather than a fine silver decorative or functional antique piece. It features a circular flat design with a central round hole, typical of fasteners used in construction, machinery, or furniture assembly to distribute load evenly.
Key Features
Flat annular ring geometry, uniform punched inner hole, bright zinc/metallic finish.
Material & Composition
Base metal with metallic plating (likely zinc-plated steel, stainless steel, or nickel-plated steel); no precious silver content observed.
Finish & Decoration
Smooth metallic polish with mild zinc passivation/plating sheen; completely utilitarian without decorative engraving or ornamentation.
Hallmarks & Stamps
None visible. Lacks silversmith hallmarks, purity marks, or maker stamps.
Construction Details
Machine die-punched and stamped from a flat sheet metal stock with tumble-polished edges.
Functional Features
Central clearance hole designed to distribute load under a threaded fastener bolt or screw.
Handle & Grip Details
None (non-handled mechanical component).
Craftsmanship Details
High-volume, automated industrial stamping and deburring.
Authentication Indicators
Absence of silver hallmarks, characteristic stamped edge quality of sheet metal hardware, non-precious metallic appearance.
Origin & Manufacturing
Standard global industrial mass production.
Era & Period
Modern / Contemporary Industrial Era (Late 20th to 21st Century).
Age Estimate
Modern (c. 1990s - present).
Cultural Significance
Represents modern mass production utility and standard mechanical engineering hardware.
Condition Notes
Good overall hardware condition; minor surface micro-scratches and slight edge wear typical of hardware stored loose.
Value Estimate
Nominal hardware value (under $0.25 USD).
Care & Maintenance
Keep dry to prevent rust or corrosion depending on base metal composition.
Similar Pieces
Standard hardware fasteners, fender washers, split lock washers, shim rings.
Interesting Facts
While not a piece of decorative silverware, flat washers date back centuries in early metallurgy to protect wood and soft metals from bolt pressure during assembly.
