3M 7010339832 Flame Resistant Hook Fastener 4in X 50yd Black

Product Description

The 3M 7010339832 is a flame resistant woven nylon hook fastener sold in a 4-inch-wide by 50-yard roll. It carries no adhesive backing and relies entirely on mechanical engagement with a mating loop fastener. The engaged thickness measures 0.15 inches. This fastener is rated for continuous use up to 250 degrees F and meets F.A.R. 25.853 paragraph (a)(1)(i), the 60-second vertical burn test standard required in aviation and aerospace interior applications. Installation requires no tools beyond a cutting implement, and the reclosable design allows repeated open-and-close cycles without significant performance loss.

This hook fastener is designed for use in applications where flame resistance is a regulatory or safety requirement. Typical uses include aircraft cabin interiors, protective garments, flame-resistant fabric panels, and industrial textile assemblies. The woven nylon construction is preshrunk for dimensional stability and is compatible with both machine washing and dry cleaning, making it suitable for garment and soft-goods applications that require periodic laundering. Fabricators, aircraft interior technicians, and industrial sewers are the primary installers.

Key Features

• Flame resistant construction meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test
• Temperature resistant to 250 degrees F continuous service
• No adhesive backing — woven hook attaches via mechanical engagement only
• 0.15-inch engaged thickness for a low-profile, tailored appearance
• Preshrunk nylon for maximum dimensional stability and flatness
• Washable and dry cleanable for garment and soft-goods use
• Mates with 3M SJ3418FR loop fastener

Compatibility

Designed to mate with 3M SJ3418FR flame resistant loop fastener. Suitable for flame resistant garments, aircraft interior panels, and industrial fabric assemblies requiring reclosable fastening with verified burn-test compliance.

Installation Notes

Attachment is typically accomplished by sewing the fastener strip directly to the substrate fabric. No adhesive activation or heat setting is required. Ensure the mating loop strip (SJ3418FR) is oriented correctly before final stitching. When used in aviation applications, verify that the completed assembly meets all applicable FAA or customer-specified interior flame resistance requirements before installation in the aircraft.
