3M 7000051961 Flame Resistant Loop Fastener 3/4in X 50yd

Product Description

The 3M 7000051961 is a flame resistant reclosable loop fastener designed for applications where fire performance is a code or specification requirement. The woven nylon loop material is coated with a synthetic rubber based adhesive that maintains bond strength at elevated temperatures. It meets the F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test, making it suitable for aerospace interiors and other regulated environments. The fastener mates with 3M SJ3519FR hook tape (sold separately, beige). This roll measures 3/4 inches wide by 50 yards long and is supplied in black.

This loop fastener is used in commercial aerospace, transportation, and industrial assembly applications where flame resistance is required by specification. It bonds to a range of substrates including paper, cardboard, painted and bare metal, glass, sealed wood, and many plastics. Installation is performed by fabricators, MRO technicians, and assembly personnel working on interior panels, equipment enclosures, and similar structures that must pass vertical burn certification testing.

Installation Notes

Surface preparation is critical for adhesive-backed fastener tapes — clean and dry the substrate before application. Apply firm pressure along the full length of the tape to ensure full adhesive contact. For regulated aerospace or transportation installations, verify that the complete fastener assembly meets applicable burn test requirements before use. Minimum order quantity is 4 rolls per order.
