Description

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.

Specifications

Installation

Step 1: Snap the serrated lower leaf onto the frame edge for temporary positioning. Step 2: Check alignment. Step 3: Drive screws through the slotted upper holes for permanent attachment. The slot allows ±3mm horizontal adjustment after snapping.

Applications

Picture frame manufacturing requiring field adjustment, panel-to-frame joins needing temporary hold during glue cure, display cabinet assembly, and light-duty door framing.

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.

FAQ

What screw sizes fit the 8320's slotted holes?

The 17mm slot accepts M3 to M4 screws. Pan-head and round-head styles both fit. Countersunk screws are not recommended as they may not seat correctly in the oval slot.

How much lateral adjustment does the slot provide?

The 17mm slot with 6mm screw head allows approximately ±3mm of horizontal adjustment before tightening. For greater adjustment, use the full 23mm slot width with a smaller M3 screw.

Is the 8320 suitable for heavier doors?

For panel loads exceeding 1kg, use three or more 8320 hinges spaced evenly. For very heavy doors, consider a larger hinge such as the 6241 series.
