Brass Threaded Ultrasonic Inserts are precision-machined threaded inserts designed to be permanently embedded into thermoplastic components using ultrasonic insertion technology. These inserts provide strong, wear-resistant internal threads in plastic parts, improving load-bearing capacity and extending product life.

The Brass Cross Insert is a high-quality threaded insert designed to provide strong, durable threads in materials such as plastic, wood, or soft metals. Manufactured from corrosion-resistant brass, this insert ensures excellent conductivity, heat resistance, and long-term performance. Its unique cross-knurled outer surface enhances grip and pull-out strength, making it ideal for demanding applications in electronics, furniture, automotive, and industrial assemblies.
