3M 7010314736 Dual Lock Reclosable Fastener SJ3442 Black

Product Description

The 3M 7010314736 is a plain-backed, no-adhesive reclosable fastener sold in a 0.75-inch-wide by 50-yard roll. This is the SJ3442 version of the 3M Dual Lock system, finished in black, with 170 mushroom-shaped stems per square inch. When two mating strips are pressed together, the interlocking stems generate high tensile strength sufficient to replace conventional mechanical fasteners such as screws, rivets, and clips. The engaged thickness measures 0.16 inches. The roll weighs 2.5 pounds. It is installed by technicians and assemblers across transportation, electronics, business equipment, machinery, medical device, and sign and display applications.

This fastener is suited for applications where repeated open-and-close cycles are required without adhesive backing. Typical installations involve mating two SJ3442 strips face-to-face to secure panels, covers, or components that need periodic removal. The 50-yard roll length supports high-volume production runs or extended field installation work. The black finish is appropriate for exposed or visible assemblies where color matching matters.

Key Features

• 170 stems per square inch for high tensile holding strength
• No adhesive backing — mechanical engagement only
• Engaged thickness of 0.16 inches for low-profile assemblies
• 0.75-inch width provides a consistent fastening strip
• 50-yard roll supports production and field use
• Black finish suits visible or color-matched installations

Compatibility

Designed for use with mating 3M Dual Lock reclosable fastener strips. Suitable for transportation, electronics, business equipment, machinery, medical, and sign and display assembly applications.

Installation Notes

Cut strips to the required length using a sharp utility knife or shears rated for tape stock. Ensure mating surfaces are clean and free of oils or debris before applying the fastener strips. Press mating stems firmly together with uniform hand pressure to fully engage the interlocking heads. When separating engaged strips, peel at an angle rather than pulling straight apart to reduce required force.
