3M 7010292639 Dual Lock Reclosable Fastener SJ3442 Black

Product Description

The 3M 7010292639 is a plain-backed, no-adhesive reclosable fastener sold as a 6-inch-wide by 50-yard roll in black. It features 170 mushroom-shaped stems per square inch and an engaged thickness of 0.16 inches. When two mating strips are pressed together, the interlocking stems generate tensile strength sufficient to replace conventional mechanical fasteners. Licensed HVAC technicians, electricians, and industrial equipment mechanics use this fastener type for panel retention, wire management, and component mounting where tool-free reclosability is required.

This fastener roll suits applications across transportation, electronics, business equipment, machinery, medical devices, and sign and display installations. The plain-backed construction means the installer applies their own adhesive or mounting method, giving flexibility for bonding to a wide range of substrate types and surface profiles. The 50-yard roll length supports production-volume cutting or field use where multiple pieces are needed from a single supply.

Key Features

• 170 stems per square inch for high-tensile interlocking hold
• Engaged thickness of 0.16 inches keeps profile low after mating
• Plain-backed, no adhesive — installer-applied mounting method
• Black color finish suits concealed or industrial installations
• 50-yard roll length supports high-volume or repeat-cut use
• Suited for transportation, electronics, machinery, medical, and display markets

Compatibility

Designed as a reclosable fastener strip for use wherever mating Dual Lock stem-type surfaces are required; plain-backed format is compatible with installer-selected adhesives or mechanical attachment across a broad range of substrates.

Installation Notes

Installation is typically performed by the trade professional whose scope covers the equipment or surface being fastened. Power down any electrical equipment before applying fastener strips near live components. Cut to length with sharp scissors or a utility knife and a straightedge. Ensure mating surfaces are clean and dry before applying any supplemental adhesive to achieve full bond strength.
