8320 Black Double-Hole Snap Hinge – Dual-Mechanism Versatile Frame Hinge
The 8320 Black Double-Hole Snap Hinge offers a unique dual-mechanism design: the upper leaf features two large oval mounting holes (17×11mm slot) for conventional screw attachment, while the lower leaf carries a serrated grip edge for direct snap-mount onto frame mouldings. This versatility makes the 8320 adaptable to multiple assembly methods on the same production line.
Dual-Mechanism Design Explained
The upper section (23mm wide, 7mm height) contains an open rectangular slot that accepts a range of screw head sizes, allowing the hinge position to be adjusted after initial placement. The lower section snaps onto frame mouldings using the serrated edge, providing immediate temporary hold until screws are driven.

Comparison with E1429B and Black Large Folding Hinge
The 8320 Black Double-Hole Snap Hinge bridges the gap between the snap-only E1429B (T01) and the screw-only large folding hinges (T12/T13). Its slotted design is the only XKY hinge allowing post-installation lateral adjustment.
