3M 7010383521 Dual Lock Reclosable Fastener SJ3460 Clear

Product Description

The 3M 7010383521 is a clear, plain-backed reclosable fastener sold as the SJ3460 under the Dual Lock product line. It features 250 mushroom-shaped stems per square inch, delivering a firm mechanical engagement when two mating surfaces are pressed together. The engaged thickness measures 0.160 inches. This fastener ships in a 2-inch-wide by 50-yard roll, making it well suited for professional installation across a range of attachment applications. It is installed by sewing onto fabric substrates or by stapling onto wood and similar rigid materials. Trade installers and fabricators working with upholstery, signage, or fixture mounting will find this format efficient for high-volume use.

The SJ3460 fastener is designed for applications where a clean, reclosable bond is needed without adhesive backing. Typical use cases include fabric attachment in upholstered panels, trade show displays, and fixture mounting to wood or engineered wood substrates. The plain backing allows the installer to choose the most appropriate mechanical attachment method for the substrate. The clear construction keeps the fastener visually unobtrusive in finished assemblies.

Key Features

• 250 stems per square inch for firm reclosable mechanical engagement
• Engaged thickness of 0.160 inches
• Clear construction for low-visibility installations
• Plain backing compatible with sewing onto fabric substrates
• Staple-compatible for attachment to wood and similar rigid substrates
• 2-inch-wide by 50-yard roll format for high-volume or continuous runs

Compatibility

Designed for use with mating Dual Lock reclosable fastener strips on fabric, wood, and similar substrates where mechanical reclosable attachment is required.

Installation Notes

Sewing applications should use a needle and thread appropriate for the fabric weight being joined. When stapling to wood or similar substrates, ensure staples penetrate cleanly through the plain backing without distorting the stem field. No adhesives or surface primers are required for mechanical attachment methods. Always confirm substrate compatibility before committing to a full run.
