The G1321 Black Zinc Single-Hole Hinge is the lightest hinge in the XKY Framing catalog at just 0.8g. The single-hole octagonal-profile design minimises material while retaining sufficient rigidity for thin craft boxes, gift packaging, and miniature display cases that prioritise low weight and a minimal footprint.

Can the G1321 support a lid with glass or acrylic insert?

For lids with glass inserts, the G1321 is suitable only for panels up to 80g (e.g., very thin acrylic under 2mm). For heavier inserts, use the 2025 or 2525 series hinges.

What is the smallest screw compatible with the G1321?

The 3.5mm hole accommodates M2 to M3 screws. M2 × 4mm flat-head micro screws provide the cleanest finish on thin-wall applications.

Is the G1321 available in a silver or gold finish?

Currently available in matte black only. For gold or antique brass finishes for premium gift boxes, contact XKY Framing for custom finishing options.

G1321 Black Zinc Single-Hole Hinge – Ultra-Lightweight Mini Hinge

The G1321 Black Zinc Single-Hole Hinge is designed for applications where every gram matters. At just 0.8g per unit, it is the lightest hinge in the entire XKY Framing range, making it ideal for premium gift boxes, miniature display cases, and thin craft enclosures where additional hardware weight would affect the product’s perceived quality or postal shipping class.

Octagonal Leaf Profile

The bevelled octagonal cuts on each leaf corner reduce material by approximately 20% compared to a rectangular leaf of the same dimensions, contributing to the exceptional 0.8g weight. The geometric profile also adds a decorative element visible on open-backed box designs.

Specifications

Installation

The single 3.5mm hole per leaf is designed for M3 × 5mm flat-head screws or brad nails. For craft paper-covered boxes, a brass eyelet-pin attachment is also compatible.

Applications

Ultra-thin gift boxes (paper-over-board, 2–4mm total wall), miniature hinged display frames, jewellery envelope flaps, greeting card hinges, model ship hatches, and doll’s house furniture.

Weight Comparison in the XKY Range

The G1321 at 0.8g is nearly half the weight of the next lightest (6220 at 1.4g) and a fraction of the heaviest (6241 at 6.7g). When 200+ hinges per product batch are used, the G1321’s weight advantage translates to measurable shipping cost savings.
