Parts Desk Insights
Best use case: Insulation pins are the correct mechanical fastening method for acoustic insulation panels in engine compartments where vibration, heat, and moisture can cause adhesive-only installations to fail over time. The perforated base plate bonds into the insulation foam while the pin passes through, and the speed washer locks the assembly in place — providing a secure mechanical hold that won’t loosen with engine vibration. Use in combination with the Soundown Acoustic Insulation Barrier and Soundown Mylar Scrim Seam Tape for a complete insulation system. Typically used at 6–8" spacing across the panel face for best retention.
