3M 7010383531 Dual Lock Reclosable Fastener SJ3442

Product Description

The 3M 7010383531 is a plain-backed, no-adhesive reclosable fastener strip sold under the Dual Lock SJ3442 designation. It features 170 mushroom-shaped stems per square inch that interlock with a mating strip to create a high-tensile mechanical bond capable of replacing traditional fasteners. The strip is black, measures 0.5 inches wide by 50 yards in length, and has an engaged thickness of 0.16 inches. Installers in transportation, electronics, industrial equipment, and sign and display applications use this fastener where a repositionable, tool-free mechanical connection is required.

This fastener strip is suited for both light commercial and industrial settings. Common applications include securing panels in vehicles and equipment enclosures, mounting electronics and control components, attaching signage and displays, and organizing wiring in machinery. Because it carries no adhesive backing, it relies entirely on the stem-to-stem interlock for retention, making it appropriate for surfaces where adhesive residue is undesirable. The roll format simplifies field cutting to custom lengths.

Installation Notes

This fastener is installed by pressing the two mating stem surfaces firmly together until the stems interlock. No tools are required for engagement or release. When used on or near electrical enclosures or control panels, de-energize the equipment before mounting. Cut to length with standard shears or a utility knife on a stable surface.
