PKN Anchor (quick-set nail)

The PKN anchor (quick-set nail) is a simple means for installation in concrete and brick bases and for hanging light structures. The anchor’s design is an elongated flat sleeve made of spring steel. On the front side the sleeve has a conical widening that prevents the fastener from falling into the hole. The other end of the sleeve has a narrowed chamfer to ease installation into the material. The recommended hole diameter is slightly smaller than the anchor’s outer diameter. During installation the sleeve body springs apart — this achieves secure fixation of the fastener in the material. Diameter from 6 to 8 mm, length from 30 to 150 mm.

The PKN anchor is installed simply:

• a hole is drilled in the concrete, brick, or stone base;
• the hole is thoroughly cleaned of debris, dust, and material residue (this step significantly affects the strength of the anchor’s fixation);
• the anchor is driven into the prepared hole with slight force.

Applications

Low-carbon spring steel is used to manufacture PKN anchors. Corrosion protection — electrolytic zinc coating of the anchor surface.

The properties of spring steel allow the fastener to spring apart inside the hole and fix itself in place. This provides simple and fast installation without additional operations or tools: it is enough to drive the anchor into the prepared hole with slight force. The flip side of this simplicity: PKN-type fasteners are used only for installing light structures. Significant weight applied to the anchor can pull it out of the material — the spring properties of the sleeve are not sufficient for fixation in this case.

The recommended anchor embedment depth and the installation depth of the external fastener (studs, rods, etc.) inside the anchor itself should be observed. For reliable fixation the anchor must be fully recessed into the hole.

FLOK supplies PKN anchors wholesale and retail.
