3M 7010383532 Dual Lock Reclosable Fastener SJ3442 Black

Product Description

The 3M 7010383532 is a plain-backed, no-adhesive reclosable fastener sold in a 2-inch-wide by 50-yard roll. It uses a mushroom-shaped stem design with 170 stems per square inch that interlock under pressure to create a high-tensile mechanical bond. The engaged thickness is 0.16 inches. This fastener replaces traditional mechanical hardware in applications where repeated attachment and detachment is required. It is installed by trade professionals and OEM assemblers across a wide range of industries where a clean, tool-free reclosable connection is needed.

This fastener is used in transportation, electronics, business equipment, machinery, medical devices, and sign and display applications. Its plain-backed construction means no adhesive layer is present, making it suited for installations where the fastener is bonded or sewn directly to a substrate. The 50-yard roll length supports production-line and large-scale service applications. The black color blends into dark panels and enclosures commonly found in equipment and signage assemblies.

Key Features

• 170 stems per square inch for high-density interlocking grip
• 0.16-inch engaged thickness for low-profile assemblies
• Plain-backed construction with no adhesive layer
• Black color suited for dark panels and enclosures
• 2-inch width by 50-yard roll for production or large-scale use
• Mushroom-shaped stem design delivers tensile strength capable of replacing mechanical fasteners

Compatibility

Designed for use as a reclosable mechanical fastener in transportation, electronics, business equipment, machinery, medical, and sign and display applications where repeated attachment and release cycles are required.

Installation Notes

Installation is typically performed by assembly technicians or trade professionals working with panel mounting, equipment enclosures, or display systems. The plain-backed surface requires bonding, sewing, or mechanical retention to the substrate prior to use. Ensure mating fastener stems are properly aligned before pressing together to achieve full tensile engagement. Follow the substrate manufacturer and any applicable industry guidelines for surface preparation and fastener retention method.
