3M 7000049007 Flame Resistant Hook Fastener 5/8in X 50yd

Product Description

The 3M 7000049007 is a flame resistant, woven nylon hook reclosable fastener supplied on a 50-yard roll, 5/8 inch wide, in black. The hook side is coated with a synthetic rubber based adhesive engineered to meet F.A.R. 25.853 paragraph (a)(1)(i), the 60-second vertical burn test requirement. The backing bonds to a wide range of substrates including paper, cardboard, painted and bare metal, glass, sealed wood, and many plastics. It is designed for applications where both secure reclosable fastening and flame resistance are required in the same assembly.

This fastener roll is suited for aerospace, transportation, commercial, and industrial applications where FAR flame resistance compliance is needed. It is used by technicians and assemblers working on interior panels, equipment enclosures, cable management, and other installations where reclosable attachment points must meet strict fire performance standards. The 5/8-inch width is a common choice for moderate-load attachment points on flat or lightly contoured surfaces.

Key Features

• Meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test for flame resistance
• Woven nylon hook construction for durable, repeated open-and-close cycles
• Synthetic rubber based adhesive provides high-temperature performance
• Bonds to paper, cardboard, bare and painted metal, glass, sealed wood, and many plastics
• Mates with 3M SJ3518FR loop fastener for a complete flame resistant system
• 5/8-inch width on a 50-yard roll for flexible cut-to-length application

Compatibility

Designed to mate with 3M SJ3518FR flame resistant loop fastener as a matched hook-and-loop pair. Suitable as a flame resistant hook fastener for reclosable attachment systems requiring FAR 25.853 compliance.

Installation Notes

Surface preparation is critical — clean the substrate free of dust, oil, and moisture before applying the adhesive-backed hook strip. A licensed technician or qualified assembler should handle installations subject to FAR compliance requirements, as the finished assembly may require documentation. Apply firm pressure across the full length of the strip to ensure full adhesive contact. Avoid stretching the fastener during application, as this can reduce bond area and long-term adhesion.
