Twister Fastener™ (Blind Fastening)

Description

The Twister Fastener™ is a patented high strength blind fastener designed to outperform traditional rivet nuts and threaded inserts in thin sheet metals and composite materials. Its unique expanding geometry transfers load away from the installation hole, significantly reducing localised stress and improving pull-out and shear performance.

Material

• Body & Expansion Elements: Stainless steel
• Integrated Sealing Gasket: Elastomeric polymer (vibration damping & moisture sealing)
• Thread Retention: Pre-applied thread locking feature
• Finish: Natural stainless steel (corrosion resistant)

Key Advantages

• Up to 3× higher pull-out strength in equivalent materials versus alternative solutions
• Superior performance in thin sheet and composite substrates
• Reduced stress cracking due to distributed load path
• Blind-side installation with no rear access required
• Integrated sealing and vibration resistance

Technical Dimensions

Installation

Blind-side installation using a standard insertion tool. The fastener expands behind the substrate to create a secure mechanical lock without rear access.
