UK specialist fastener distributor, Star Fasteners, has collaborated with Arconic to produce the Penta-Lok – a fastener specifically designed for the composite panel market.
Due to its high pull-out strength, Penta-Lok is suited for use within thin materials or delicate composites and within misaligned, oversized, or slotted holes, and its uniquely engineered peel system installs with ease into shallow panels. It is an easy-to-install, 6.4mm diameter, plated steel, peel fastener with superior blind side strength. It has a neat domed head and its positive mechanical pin retention ensures structural integrity.
If the tip of the body is inserted into material (minimum 8mm composite panel) the Penta-Lok will do the rest. The installation process seats the flange to the surface of the material as it claws itself in on the blind side; resulting in a supportive load spread of approximately 16mm.
Penta-Lok’s reduced flange diameter also enables installation against raised profiles and has been specifically designed for the secure fastening of profiled cargo load restraint and areas with restricted space, such as door gear and latches.
“As Huck®’s largest UK distributor it was only natural that we turned to Arconic for collaboration on producing a fastener based on a requirement we had recognised, and we are really excited to bring the Huck Penta-Lok to the market,” says Nicola Smith, managing director at Star Fasteners.
“We recognised a gap in the market for a mechanical blind fastener that can be quickly installed in the multiple variations of composite panel. The ever-evolving lightweight panels are being used in a wide range of applications, including the Polyfont UK Ltd range of GRP composite panels,” comments Nicola. “Penta-Lok also performs well in a broad spectrum of plastic, honeycomb aluminium and multi composite boards.”
