Key Differences Between 3M Dual Lock and Scotch Extreme Fasteners?

Understand the Material

One of the main differences between these two fasteners is the material they are made from. 3M Dual Lock is made from polyolefin. This material is durable and weather-resistant. On the other hand, Scotch Extreme Fasteners use Velcro as their base material. Velcro is less robust than polyolefin and is not as weather-resistant.

Evaluate the Strength

Strength is another area where these two products differ. 3M Dual Lock offers a higher holding strength, capable of supporting up to 5 pounds. Scotch Extreme Fasteners, however, can support a maximum weight of up to 2 pounds. If you need to hold heavier items, 3M Dual Lock is your best bet.

Consider Where to Use

The next thing to think about is where you will use the fasteners. 3M Dual Lock works well both indoors and outdoors. Its weather-resistant properties make it suitable for any environment. In contrast, Scotch Extreme Fasteners are designed for indoor use only.

Ease of Use

Scotch Extreme Fasteners are very easy to use. Just peel the backing off and stick them to the surface. It’s as simple as that. 3M Dual Lock takes a bit more effort. You need to align the two strips properly to make sure they lock securely.

Check for Weather Resistance

If you are planning to use the fasteners outdoors, weather resistance is crucial. 3M Dual Lock is weather-resistant. This makes it ideal for outdoor projects. Scotch Extreme Fasteners lack this feature, limiting their utility to indoor projects.

Reusable or Not

Good news! Both these fasteners are reusable. 3M Dual Lock can be detached and reattached without losing its holding strength. Scotch Extreme Fasteners offer the same benefit. This feature makes both options eco-friendly and cost-effective.
