Velcro & Dual Lock Fasteners

Aircraft Hook-and-Loop Fasteners

Hook-and-loop fasteners—commonly referred to as Velcro—use complementary hook and loop surfaces to create a removable attachment. They are useful when aircraft components, covers, cushions, equipment or other items need to be removed periodically for maintenance or inspection.

Depending on the specific product, hook-and-loop fasteners can be supplied in different widths, lengths, configurations and adhesive options. Always verify the product's individual specifications and adhesive suitability for the intended substrate and service environment.

3M Dual Lock Reclosable Fasteners

3M Dual Lock is a reclosable fastening system that uses interlocking mushroom-shaped stems rather than conventional hook-and-loop construction. When the mating surfaces are pressed together, the stems interlock to create a secure, removable attachment.

Dual Lock can be useful where a stronger, more rigid removable attachment is desired than conventional hook-and-loop fasteners provide. Product performance varies by Dual Lock type, adhesive, substrate and environmental conditions.

Common Aviation Applications

Choose the Right Reclosable Fastener

Important Aviation Maintenance Considerations

For aircraft applications, select the specific fastener and adhesive system based on the applicable aircraft maintenance manual, engineering instructions, component documentation or other approved technical data. Consider the substrate, temperature, vibration, moisture, cleaning chemicals, required attachment strength and frequency of removal.

Adhesive-backed fasteners also require appropriate surface preparation and installation procedures. Product-specific technical data should be reviewed before installation to confirm compatibility and performance requirements.

Frequently Asked Questions

What is aircraft Velcro?

Aircraft Velcro is a common industry term for hook-and-loop fastening products used in aviation maintenance and aircraft interior applications. The two mating surfaces use hooks and loops to create a removable attachment.

What is the difference between Velcro and 3M Dual Lock?

Conventional hook-and-loop fasteners use hooks that engage loops. 3M Dual Lock uses interlocking stems on both mating surfaces. Dual Lock generally provides a more rigid reclosable attachment, while hook-and-loop products provide a flexible fastening system.

Can hook-and-loop fasteners be used on aircraft?

Hook-and-loop fasteners are used in various aircraft interior, equipment and maintenance applications. For installation on an aircraft, always verify that the specific fastener and adhesive are permitted for the intended application and substrate by the applicable maintenance or engineering documentation.

Are 3M Dual Lock fasteners reusable?

Yes. Dual Lock is designed as a reclosable fastening system, allowing the mating surfaces to be separated and reattached. The number of useful open-and-close cycles depends on the specific product and application.
