Ultrasonic Inserts

Ultrasonic inserts are threaded fastener components installed in compatible thermoplastic parts to create a threaded connection point. They are used in commercial assembly, fabrication, repair, and production work when components need to be attached to thermoplastic material with a specified thread size and insert profile.

Use Cases

Add threaded fastening points to thermoplastics

Ultrasonic inserts are used where a thermoplastic part needs a defined threaded connection for a compatible fastener. They support assembly, fabrication, repair, and repeat production work.

How to Choose

Start with thread and profile

Match the insert to the required metric or inch thread size, then choose the stated tapered, flush straight, or flanged straight profile. For tapered options, also confirm whether a single-vane or double-vane design is required.

Applications

For compatible thermoplastic components

These inserts are intended for installation in thermoplastic parts and components. Select the configuration that matches the threaded fastening point required by the assembly.

Planning Guide

Plan the right fit before choosing

Thread Selection

Match the insert to the fastener requirement

The listed assortment includes both metric and inch thread sizes. Selecting the correct thread is the first step toward creating a compatible threaded fastening point in a thermoplastic part.

  • Metric sizes represented include M3-0.5, M4-0.7, and M6-1.0.
  • Inch sizes represented include 4-40, 8-32, 10-32, 1/4-20, 3/8-16, and 3/8-24.
  • Use the stated thread size to match compatible fastener requirements.
Profile Selection

Compare tapered, flush straight, and flanged straight formats

Insert profile is a central selection factor. Tapered inserts are available with single-vane or double-vane designs, while straight inserts are offered in flush and flanged configurations.

  • Tapered inserts are represented in single-vane and double-vane styles.
  • Flush straight inserts are available for applications requiring a flush profile.
  • Flanged straight inserts provide the stated flanged profile for thermoplastic assembly work.
Quantity Planning

Choose a pack size that fits the work ahead

Package quantities vary across the assortment, allowing buyers to choose an amount aligned with a repair task, planned assembly work, stocking needs, or production requirements.

  • 25-count packages are represented for project, repair, or stocking needs.
  • 50-, 100-, 250-, and 500-count options support repeat assembly needs.
  • A 1,000-pack option is represented for larger assembly or production requirements.
