PRODUCT FAQ
-
What is the maximum weight this fastener can hold?
The 3M™ Dual Lock™ Reclosable Fastener SJ3540, Black, 1 1/2 in x 50 yd, Type 250 can hold up to 5 pounds per square inch.
-
Can this fastener be used on fabric surfaces?
Yes! The SJ3540 reclosable fastener works well for a variety of surfaces including painted walls, glass and bare metal. It also works with many plastics (polyolefins).
-
Is it difficult to remove once attached?
Not at all! Although the bond is strong while connected, removal is easy thanks to the "peel-apart" construction design that lets you quickly and easily pull items apart when you want.
-
How long does each pack last generally before needing replacement?
A single case of one roll typically lasts a long time because there are roughly fifty yards on each spool. This allows for extensive use across countless projects.
-
; Is it waterproof?
; No! While our SJ3540 dual lock fasteners use an incredibly secure gripping surface powerfully strong enough that they stay locked until explicitly pulled apart— They aren't immune from moisture-related issues despite being made safe from chemicals such as detergents or wetting agents.
Durable and secure, 3M™ Dual Lock™ Reclosable Fastener SJ3540 has exceptional strength through its interlocking mushroom-shaped heads (250 stem density per square inch), providing up to 5X the tensile strength of typical hook-and-loop products. This fastener was designed with a synthetic rubber-based black PE foam tape protected by a removable, film liner. This pressure sensitive adhesive features quick stick and a short dwell time. With 3M™ Dual Lock™ Reclosable Fastener SJ3540, there is no need for any drilling, screwing or sewing tools which makes for quick installation.

3M™ Dual Lock™ Reclosable Fastener SJ3540 consists of interlocking mushroom-shaped heads that easily slide over each other, allowing for positioning of parts before being snapped together. This fastening process creates a durable attachment and provides fast product assembly with great design flexibility. These reclosable fasteners can also engage with different stem densities for varying levels of strength and system performance.
3M™ Dual Lock™ Reclosable Fasteners sound an audible snap when secure, which verifies closure of the attachment. To disengage, simply peel the pieces apart by hand. These fasteners maintain their strength throughout multiple attachments and detachments. A lightweight alternative to metal fasteners, this product remains hidden beneath surfaces and does not interfere with the integrity of your material—providing aesthetic improvements and design flexibility.
Hundreds of Reattachments in a SnapWhen two pieces of 3M™ Dual Lock™ Reclosable Fasteners mate, the stems flex and the mushroom heads slide past each other. After passing the opposing mating piece, the stems snap back into their original position and the opposing mushroom heads interlock. These fasteners can provide high tensile strength but can be opened by simply cleaving or peeling open the closure. This product is well suited for many indoor applications where a good performance, high strength, reclosable fastening system is required.
Delivers Long-Lasting PerformanceNot all design requirements are easily satisfied, but you can simplify your attachments. When you need a strong, reliable, yet removable closure, 3M™ Dual Lock™ Reclosable Fasteners are the easy alternative to traditional fastening methods such as screws, nuts or bolts.
