Gold-Tone Brass Rectangular T-Nut Fastener
Hardware Fastener (Industrial T-Nut) · None (Gold-Toned Brass/Alloy). The color is characteristic of industrial brass (copper-zinc alloy) rather than precious gold.
Purity: 0K - Not Gold. This is a base metal alloy (likely brass or gold-zinc plated steel) commonly used in furniture or mechanical assembly.
Type
Hardware Fastener (Industrial T-Nut)
Purity
0K - Not Gold. This is a base metal alloy (likely brass or gold-zinc plated steel) commonly used in furniture or mechanical assembly.
Gold Type
None (Gold-Toned Brass/Alloy). The color is characteristic of industrial brass (copper-zinc alloy) rather than precious gold.
Weight
1.5 - 3.0 grams. Industrial hardware of this size is typically dense but light due to its small footprint.
Description
A small, gold-toned rectangular metal block featuring a central threaded hole. While the color mimics gold, the geometry and threading identify it as a T-nut or captive nut used in structural assemblies.
Key Features
Internal threads for screw engagement, flat rectangular 'wings' to prevent rotation in a recessed slot, and a characteristic industrial brass sheen.
Color & Finish
Mustard-yellow brassy hue with a machined finish. The surface shows industrial tool marks and a semi-reflective, unpolished luster typical of bulk hardware.
Hallmarks & Stamps
None visible. Precious gold items require purity hallmarks (e.g., 585, 750); industrial fasteners typically lack markings or may have a manufacturer's batch code on the reverse.
Dimensions Estimate
Length: 10mm-12mm, Width: 5mm-6mm. Central threaded aperture appears to be M3 or M4 metric sizing.
Gemstones & Inlays
None. This is a functional mechanical component.
Clasp & Closure
Internal threading. Designed to receive a machine screw or bolt to secure two components together.
Chain & Links
N/A. This is a solid machined block.
Craftsmanship Details
Precision machined. The central hole is drilled and tapped with consistent pitch. The edges are slightly chamfered to allow for easier insertion into a guide-way.
Authentication Indicators
Red flags for gold authentication: Presence of a threaded hole (highly unusual for jewelry), lack of hallmarks, and the specific 'brassy' greenish-yellow undertone.
Origin & Maker
Unknown industrial manufacturer. Mass-produced in high volumes, likely from a hardware supplier in China or Southeast Asia.
Era & Period
Modern / Contemporary Industrial. Standard used in modular furniture (flat-pack) and electronics assembly from the late 20th century to present.
Age Estimate
Likely manufactured within the last 10-20 years based on the lack of oxidation/patina and modern machining precision.
Cultural Significance
Represents the standardization of global manufacturing and the utility of copper-based alloys in non-decorative infrastructure.
Condition Notes
Good. Minimal threading wear is visible. Surface shows standard micro-scratches from bulk handling. Grade: Functional/Standard.
Value Estimate
Melt Value: Negligible (less than $0.05 USD). Retail Value: $0.10 - $0.50 as a replacement hardware component.
Care & Maintenance
Keep dry to prevent oxidation (verdigris). If used in assembly, avoid over-torqueing the threads to prevent stripping the brass alloy.
Similar Items
Gold-plated silver (Vermeil) beads or findings; however, these lack the internal threading and structural thickness of this industrial part.
Interesting Facts
Brass is often called 'Poor Man's Gold' due to its similar color, but it is significantly harder and more reactive to environmental acids.
