Speedserts® - Key Features:

Speedserts self-threading inserts form strong threads in softer metals and plastics for a very high pull-out resistance. Their locking action makes them very resistant to vibration.

  • Very High pull-out resistance.
  • Suitable for a wide range of softer metals and plastics.
  • Symmetric design for automatic feeding.
  • One-step installation.
  • No metal chips.

Ideal for automatic feed installations. Symmetrical design allows inserts to be installed using either end.

Exterior lobes are designed to roll through the base material and lock the insert in place without leaving chips behind. The wave gently rolls through the base material pushing it back and then allowing it to return behind the wave crest to securely lock the insert in place.

High-quality internal threads are wear resistant. Unified and American Standard, class 2B, or ISO Metric standard, class 6H threads.

Speedserts threaded inserts are available in stainless steel in regular, medium, or short lengths.
