Dual Lock Reclosable Fastener (Mushroom Head) – Extremely Strong, Reusable Fastening of a New Generation
Dual Lock reclosable fastener, often also called the “mushroom-head” fastener, is an advanced alternative to classic hook-and-loop systems. This system uses special plastic mushroom-shaped stems, which, when pressed together, interlock and create an exceptionally strong and stable connection. Unlike traditional hook-and-loop fasteners, it provides even load distribution, high tensile and shear strength and a long service life.
Professional Quality and Structural Strength
3M Dual Lock is made from durable polyolefin, which withstands UV radiation, heat, moisture and chemicals, making it ideal for both indoor and outdoor use. Once the mushroom heads snap together, a strong mechanical joint is created that can withstand high loads, yet can be reopened at any time without damaging the material. The fastening remains quiet, clean and requires no tools.
Universal Use in Industry, Transport and Interior Design
Dual Lock reclosable fasteners are used for mounting panels, covers, illuminated signs, vehicle interior components, electronic devices, exhibition structures and structural parts. They are especially popular in applications where high joint strength is required, along with the option of easy separation. They can also be combined with 3M VHB™ pressure-sensitive adhesive, which provides instant adhesion without the need for drilling or screwing.
Main Advantages of the 3M Dual Lock (Mushroom Head) System
-
Extreme joint strength – up to 5× stronger than classic hook-and-loop fasteners
-
Reusable connection – more than 1000 opening and closing cycles
-
Resistance to UV radiation, temperature and moisture
-
Clean and quiet fastening without dust or fibres
-
Easy application – also available in self-adhesive versions
-
Compatibility between different types (e.g. 3M SJ3550, SJ3560, SJ3870)
Practical and Elegant Fastening without Drilling or Screws
Applying Dual Lock is simple – the strips are adhered to both surfaces, pressed together and the joint is immediately functional. The connection can be released by simply pulling the two parts apart, while neither the substrate is damaged nor the adhesion reduced. The fastening is strong enough for both structural and decorative applications, where a professional appearance without visible fixings is required.
The Dual Lock Reclosable Fastener (Mushroom Head) category represents the most advanced technology in reusable mechanical fastening. It combines high mechanical strength, easy handling and long service life, making it the ideal choice for professional installations, design projects and technical applications where it is important to combine strength with elegance and practicality.
