WHEN STANDARD NUTS AREN'T PRACTICAL

Get a Secure Fastening Point Without Reaching Behind the Panel

Thin sheet metal, hollow panels and enclosed spaces can make traditional nuts difficult or impossible to hold from the back.

✖️ No access to the back side of the workpiece.
✖️ Thin material may not have enough thickness for a strong tapped thread.
✖️ Loose fastening can lead to rattling, shifting or repeated repairs.
EXPANDS BEHIND THE PANEL

The Locking Body Opens Up for a Stronger Grip

Clamp the Material From the Back Side

As the fastener is tightened, the expandable body forms behind the material to lock the threaded insert securely in position.

  • Useful when rear access is limited
  • Creates a mechanically locked fastening point
  • Designed for thin panels and similar materials
  • Cleaner solution than improvised fastening methods
PETAL-SHAPED LOCKING DESIGN

Expansion Creates a Wider Hold Behind Thin Materials

Designed for Materials Where Traditional Nuts Are Hard to Install

The expandable structure opens into a petal-like shape behind the workpiece, increasing the contact area and helping resist pull-through.

  • Expandable locking body
  • Wider rear-side contact area
  • Ideal for thin and hollow materials
  • Creates a neat finished fastening point
