3M 7010383530 Dual Lock Reclosable Fastener SJ3441 Black

Product Description

The 3M 7010383530 is a plain-backed, no-adhesive reclosable fastener sold as the SJ3441 in a black finish. It features 400 mushroom-shaped stems per square inch that interlock with a mating Dual Lock strip to create a high-tensile mechanical bond capable of replacing traditional fasteners. The engaged thickness measures 0.16 inches. Each roll is 1/2 inch wide and 50 yards long, providing substantial coverage for production or field applications. Installers in transportation, electronics, industrial equipment, and signage rely on this fastener where a clean, repositionable, and hardware-free attachment method is required.

This fastener is suited for both light assembly and high-cycle reclosable applications across residential and commercial environments. Common uses include securing panels, mounting displays, organizing cable runs, attaching medical equipment components, and assembling business machine housings. Because it carries no adhesive backing, it is intended for use with a compatible adhesive or mechanical retention method to anchor it to the substrate surface. It is available in roll form for easy cutting to length on the job or at the bench.

Installation Notes

Installation is typically performed by technicians or assemblers familiar with mechanical fastening systems. Cut the strip to the required length using scissors or a utility knife before applying. Ensure mating surfaces are clean and free of oil, dust, or moisture prior to securing the fastener. Because this product has no adhesive backing, a separate bonding method must be selected based on substrate requirements.
