3M 7000052008 Flame Resistant Hook Fastener 3/4 in X 50 Yd

Product Description

The 3M 7000052008 is a flame resistant woven nylon hook reclosable fastener designed for use on garments, fabrics, and other textile applications where fire resistance is a requirement. Sold as a 50-yard roll at 3/4 inches wide, this no-adhesive hook fastener engages at 0.15 inches thickness and withstands temperatures up to 250 degrees F. It meets FAR 25.853 paragraph (a)(1)(i) 60-second vertical burn test requirements. Licensed HVAC, electrical, and industrial technicians working in aviation, transit, or other regulated environments specify this fastener where standard hook-and-loop would not meet flammability codes.

This fastener is suited for applications demanding both reclosable functionality and flame resistance. Common uses include protective garments, equipment covers, and fabric panels in aerospace, mass transit, and industrial settings. The light grey color (S023) provides a tailored, finished appearance. Because the fastener is preshrunk, it maintains dimensional stability and flatness through repeated use, washing, and dry cleaning cycles. It carries no pressure-sensitive adhesive, making it suitable for sewn-in applications only.

Key Features

• Flame resistant construction meets FAR 25.853 paragraph (a)(1)(i) 60-second vertical burn test
• No adhesive backing — sewn-in application for garments and fabric panels
• Woven nylon hook material with 0.15 inches engaged thickness
• Temperature resistant to 250 degrees F
• Preshrunk for maximum dimensional stability and flatness
• Washable and dry cleanable for reusable textile applications
• Mates with 3M SJ3418FR loop fastener

Compatibility

Designed to mate with 3M SJ3418FR flame resistant loop fastener. Intended for sewn-in use on garments, equipment covers, and fabric assemblies requiring FAR 25.853-compliant reclosable fastening.

Installation Notes

This fastener is installed by sewing — no adhesive is present, so adhesive-based mounting is not applicable. Cut to length using sharp shears and finish raw ends to prevent fraying. Follow applicable flammability regulations and textile safety standards for the end-use environment. Verify mating loop material is also flame resistant rated to maintain full system compliance.
