Types of Threaded Inserts We Manufacture

Abbott-Interfast designs and manufactures numerous threaded inserts to meet the demands of modern manufacturing. We produce each insert to exacting standards for consistent performance and long-lasting thread integrity. Our team works with engineers and purchasing teams to identify the ideal insert style for each material and application.

Ultrasonic Inserts

We engineer our threaded ultrasonic inserts specifically for thermoplastics, providing strong, permanent threads through ultrasonic vibration and heat. This process fuses the insert securely into the plastic and delivers exceptional pull-out resistance and torque strength. We produce ultrasonic inserts in various configurations to match your part geometry and resin type.

Press-In and Mold-In Inserts

Press-in inserts offer quick, straightforward installation for post-molded plastics, while mold-in inserts are positioned in the mold cavity before injection, becoming permanently anchored in the finished part. Both options provide stable, wear-resistant threads for repeated assembly and disassembly.

Specialty and Custom Inserts

For unique applications, Abbott-Interfast manufactures threaded inserts in specialized materials and configurations, featuring custom knurl configurations. Our engineers can modify dimensions, thread types, and drive styles to optimize performance under specific load or vibration conditions.



Materials

At Abbott-Interfast, material selection is key to the strength and performance of every threaded insert we produce. We offer numerous materials and finishes to match your mechanical, environmental, and cost requirements, so each insert performs reliably in its intended application. Common materials include:

  • Brass: Provides excellent machinability, corrosion resistance, and thermal conductivity, ideal for threaded ultrasonic inserts and other plastic applications.

  • Stainless Steel: Offers high tensile strength and superior resistance to corrosion and temperature extremes, suitable for demanding environments such as marine or industrial use.

  • Steel: Delivers strength and durability for structural applications; available in various grades and heat-treated options.

  • Aluminum: Lightweight yet strong, aluminum inserts are a preferred choice when weight reduction and conductivity are priorities.

  • Plastic: For lightweight, nonconductive, and corrosion-free components, plastic threaded inserts offer a cost-effective option for electronics and other nonmetallic assemblies.

Every insert we manufacture undergoes strict quality checks to ensure dimensional precision and coating consistency. Whatever your design needs, Abbott-Interfast delivers the right combination of material strength and surface protection for your application.



Engineered for Strength, Reliability, and Performance

All our threaded inserts deliver dependable performance under the most demanding conditions. We engineer each design with precision tolerances and controlled manufacturing processes to ensure secure fastening and long service life.

We test our inserts for pull-out strength, torque resistance, and vibration durability, guaranteeing stable performance in static and dynamic assemblies. Each component maintains thread integrity even under repeated installation cycles.

Essential performance advantages include:

  • Superior Thread Retention: Designed to resist stripping and loosening, even in softer base materials.

  • Vibration Resistance: Engineered geometries and material choices prevent back-out in high-vibration environments.

  • Corrosion and Heat Resistance: Available in stainless steel, brass, and specialized coatings to ensure reliability in harsh or high-temperature settings.

  • Repeatable Assembly: Precision-machined threads allow for multiple installations without degradation of performance.

Frequently Asked Questions

What are threaded inserts used for?

Threaded inserts add durable, reusable threads to materials that are too soft or thin to support a threaded fastener on their own, such as plastic, wood, or aluminum. They provide strong internal threads that allow screws and bolts to be installed and removed repeatedly without damaging the base material.

 

What are threaded ultrasonic inserts?

Threaded ultrasonic inserts are for thermoplastic applications. During installation, ultrasonic vibration generates frictional heat, allowing the insert to melt slightly into the plastic and form a secure, permanent bond once cooled. This method ensures excellent pull-out resistance and torque strength.

 

Do you handle small and large production runs?

Absolutely. Our facility can produce prototype quantities as well as full-scale production runs, ensuring consistent quality and on-time delivery, regardless of the order size.
