3M™ Dual Lock™ Reclosable Fastener SJ3560
Product Description
3M™ Dual Lock™ Reclosable Fasteners are positive locking, hidden fasteners designed for use in a variety of
attachment solutions. They consist of continuous strips of polyoleꢀn stems with a mushroom shaped top
protruding up from the backing. When snapped together the mushroom shaped caps interlock producing a
strong reliable Fastener.
The standard Dual Lock fasteners are available in three diꢁerent stem densities (170, 250 and 400) referring to
the approximate number of stems per square inch. (26, 39, 62 stems per square centimeter) By inter-locking
diꢁerent stem density combinations you can create the strength that suits your application; more total stems
give higher strength. The Dual Lock Reclosable fasteners can be mated in the following combinations of
increasing closure strength: Type 170 to Type 250, Type 170 to Type 400, Type 250 to Type 250 and Type
250 to Type 400. We do not recommend using the Type 170 to 170 because it does not have enough strength
for a good connection. We do not recommend using the Type 400 to 400 because it is too strong and may
cause stems and heads to rip out rendering the fastener no longer reclosable.
The Dual Lock Low Proꢀle has one stem density of approximately 705 stems per square inch and they
interlock to themselves. The low proꢀle products are not intended to mate to the standard size Dual Lock.
There are a variety of pressure sensitive adhesives available with Dual Lock to cover most application needs.
The pressure sensitive adhesive makes the Dual Lock easy to use, simply remove the liner, place the Dual Lock
and apply ꢀrm consistent pressure to assure good contact with the substrate you are adhering. We also oꢁer
non-adhesive backed Dual Lock for applications where the PSA does not meet your needs.
Product Features
•Easy Alignment: Dual Lock fasteners engage in any direction or position. The mushroom stems slide into
position until they are engaged by snapping together applying ꢀrm pressure, this eliminates concerns about
misalignment or spontaneous engagement.
•Positive Locking: Dual Lock fasteners engage/fasten with an audible snap and detectable movement assuring
complete and secure closure.
•Reclosability: Dual Lock fasteners can be opened and closed for multiple closure applications (high cycle
life).
•Blind Attachment: Dual Lock fasteners can be attached on the backside of substrate (i.e. trim piece) where it
will not interrupt the show surface.
•Rattle-Free: Dual Lock fasteners will not rattle loose.
•Ease of Assembly: Dual Lock fasteners can be used to attach components before they enter the ꢀnal
assembly plant, reducing the number of parts and the assembly time. No tools are required.
•Adjustable Strength: By selecting diꢁerent combinations of the various stem densities of the Dual Lock the
fastener can be designed to meet the strength needs of the designer.
•Product Forms: Dual Lock fasteners come in a variety of forms: Backed with Pressure Sensitive adhesive,
Non-woven, Rigid backed, Die Cut Shapes, and low proꢀle.
•Attachment Methods: The wide varieties of Dual Lock fasteners allow a design engineer ꢂexibility to be able
use and attach Dual Lock to just about any substrate or application. Peel and stick pressure sensitive adhesive
backed is quick and easy yet strong and secure. Non-woven backed can be used with a variety of adhesive
choices such as hot melt, liquid, epoxies, sealants, etc. We have parts that can be attached with a screw or
rivet; rigid and plain backed for developing your own special device.

Note
The following technical information and data is intended as a guideline to assist customers in selecting 3M™ Reclosable Fasteners for further evaluation. This technical
information is not product release speciꢀcations or standards. Unless stated diꢁerently, the typical system performance and product properties were obtained using
speciꢀc test methods under controlled laboratory conditions of 72°F
± 5°F and 50% ± 10% relative humidity. The user is responsible for evaluating 3M reclosable fasteners under expected use conditions to ensure suitable performance
for the intended application.
These are typical values which were gathered from testing the PSA backed materials. Similar values can be expected when the Dual Lock is held securely in a rigid
fashion.
Tests were run at 12 inches per minute

3M™ Dual Lock™ Reclosable Fastener SJ3560
Design Considerations
• As a general rule, four square inches of fastener area per pound of static tensile or shear load to be supported is suggested as a starting point for evaluation. More or
less area may be needed depending on speciꢀc conditions or end use applications. Type 250 Dual Lock Reclosable fasteners less than 0.75" (19 mm) width should not
be engaged to other type 250 Dual Lock Reclosable fastener as low disengagement values may occur.
• Whenever possible design one side of the Dual Lock reclosable fasteners to be larger than the mating side. This will allow for variability or mismatch in Dual lock
alignment positions, and ensure 100% fastening area contact. Another approach would be to design two rectangular shaped fastener pieces so that they can be
engaged in a cross web/perpendicular pattern (crossed).
• Dual Lock strength is proportional to the fastening contact area, and the number of stems in combination used. More stems and more Dual Lock used gives you more
strength, less stems combined and using less Dual Lock will give you less strength.
• Dual Lock disengagement strength/performance is strongest in direct tensile. Peel/cleavage mode is where it is most easily removed.
• Final product performance depends upon a combination of factors: the substrate and its surface characteristics, the fastener selected, the application method and
conditions, the time and environmental conditions required for the application. Because these factors are unique to each application, the user must evaluate Dual Lock
and do any testing required to determine Dual Lock’s suitability for the user’s desired end use.
