3M FlameResistant Hook Fastener SJ3419FR (50?mm roll)
Information
The 3M SJ3419FR hook fastener is engineered for aerospace environments, where reliability and flameresistance are mandatory. The product features a plain backed nylon woven substrate with Jshaped hooks (~300 hooks per square inch or ~46 hooks/cm²) that mesh with the corresponding loop fastener (SJ3418FR). The flameresistant backing (rated to ~93?°C / 200?°F) makes it suitable for aircraft interiors, avionics enclosures, and other applications requiring compliance with fire safety standards such as FAR?25.853 (for loop part) and aerospace-certified fastener systems. The absence of adhesive backing means it is typically sewn or bonded via hot melt/adhesive suitable for aerospace fabrics or substrates. Its availability in multiple widths (15.87?mm to 101.6?mm) and thicknesses adds flexibility for design engineers.
