Industrial Steel D-Ring Shackle with Serialized Identification
Hardware/Fastener (Not Silverware) · Industrial manufacturer indicated by alphanumeric code QC-B2928; likely a specialized hardware or safety equipment supplier.
Pattern: Standard Industrial D-Ring used for load-bearing or securing applications.
Type
Hardware/Fastener (Not Silverware)
Maker
Industrial manufacturer indicated by alphanumeric code QC-B2928; likely a specialized hardware or safety equipment supplier.
Material
Forged Carbon Steel or Stainless Steel; contains no silver. Surface shows oxidation consistent with steel, not tarnish on silver.
Dimensions
Approximately 3.5cm wide and 4cm high; estimated weight 40-60 grams depending on metal density.
Description
This is a utilitarian D-ring used for industrial, equestrian, or load-securing purposes. It is clearly non-precious hardware, featuring a serialized identification code 'QC-B2928' used for safety regulation and inventory tracking. The dull grey patina and surface texture are characteristic of weathered steel, a sharp contrast to the luster of fine silver.
Key Features
Serialized identification code, forged construction, non-reactive grey patina, and heavy-duty structural form.
Material & Composition
Forged Carbon Steel or Stainless Steel; contains no silver. Surface shows oxidation consistent with steel, not tarnish on silver.
Finish & Decoration
Industrial matte finish with surface pitting and scratches from use; lacks decorative precious metal treatments.
Hallmarks & Stamps
No silver hallmarks. Includes a serial number or batch code 'QC-B2928' for Quality Control and traceability.
Construction Details
Industrial drop-forging; curved bar joined to a straight base rod, designed for high tensile strength.
Functional Features
Closed loop design for attachment to webbing, cables, or hardware; rigid structure for load distribution.
Handle & Grip Details
N/A; this is a mounting component, not a handled utensil.
Craftsmanship Details
Machine-forged for durability and utility; emphasizes strength over aesthetic refinement or hand-finishing.
Authentication Indicators
Absence of silver purity marks (925, Sterling) and presence of an industrial QC code confirms this is not a silver item.
Origin & Manufacturing
Likely mass-manufactured in an industrial center (e.g., USA, Germany, or China) for hardware distribution.
Era & Period
Modern Industrial (late 20th - 21st century); utilizes modern laser or die-stamping for tracking.
Age Estimate
Modern era, likely produced within the last 10-20 years based on font style and wear.
Cultural Significance
Represents modern industrial safety and standardization rather than artistic silversmithing traditions.
Condition Notes
Good functional condition; exhibits surface scratches, minor pitting, and industrial wear consistent with outdoor or mechanical use.
Value Estimate
Nominal resale value as hardware ($1 - $5 USD); no bullion or antique silver value.
Care & Maintenance
Prevent rust by light oiling; no silver polish required. Do not use for safety-critical loads if structural integrity is questioned.
Similar Pieces
Often confused by laypersons with silver rings due to grey color, but similar to carabiners, shackles, and clevises.
Interesting Facts
D-rings of this type are critical in safety harnesses and cargo tie-downs; the 'QC' prefix likely stands for 'Quality Control.'
