Exploring the World of Inserts

Inserts are a type of fastener that plays a large role in assembly. They provide a versatile and reliable solutions for a multitude of applications. From strengthening threads to providing durable anchoring, inserts play a vital role in securing components across industries. We’ll delve into various types of inserts, exploring their common uses, installation tools required, materials, and more.

1. Barb-Serts

Barb-Serts strengthen weakened or damaged threads with multiple barbs, resisting pull-out forces. Typically made from stainless steel, brass, or aluminum, they repair stripped threads in soft materials like plastic or wood. Installation involves drilling, tapping, and driving the Barb-Sert into place using a dedicated tool.

2. E-Z Lok Inserts

E-Z Lok Inserts repair damaged or reinforce weak threads using external threads. Installed with a bolt or screw, they create a secure connection. Available in various materials, including stainless steel, brass, and carbon steel. They’re popular in automotive, aerospace, and electronics due to their easy installation.

3. Helicoil Inserts

Helicoil Inserts create strong, wear-resistant threads in materials prone to stripping. Made from stainless steel or high-strength alloys, they’re vital in aerospace, automotive, and manufacturing. Installation involves tapping the hole to a larger size, screwing in the insert using a special tool, and then tang removal.

4. Key-Locking Inserts

Key-Locking Inserts, or Keenserts, resist vibration and torque with internal threads and keys. Common in heavy machinery and high-performance vehicles, installation requires drilling, tapping, and inserting using a specific tool. These provide a secure, permanent fixing.

5. Knife Thread Inserts

Knife Thread Inserts aka Screw-Lock Inserts, are great for high-temperatures and corrosive environments with sharp, angled threads. These are great for heavy vibrations and are typically made from stainless steel or heat-resistant alloys. Used in aerospace, power generation, and industrial machinery, installation involves tapping the hole and driving or screwing the insert into place using a dedicated tool.

6. Press Inserts

Press Inserts add threads to plastic or composite materials efficiently. Featuring knurled exteriors or barbs, they’re used in consumer electronics, automotive interiors, and appliances. Installation requires heating, pressing into place, and allowing it to cool and solidify which creates a strong bond.

Inserts offer diverse solutions for enhancing thread strength, repairing damaged threads, and providing secure fastening in various materials and environments. Understanding their characteristics and installation methods empowers engineers and manufacturers to select the right solution for their specific needs, ensuring reliability and longevity in their assemblies.
