Products - Self Tapping Threaded Inserts - Bour Self Tapping Inserts

Hole Series - Key Features:

Hole Series self threaded inserts are designed for use in tough-to-tap, high-strength materials as well as softer metals and plastics.
Highest pull-out resistance.
Suitable for harder materials.
Superior vibration resistance.
One-step installation.
Available certified to military standards.

Superior pull-out resistance in softer metals and plastics from the external v-form thread.

Circular cutting elements self-tap and lock into the base material. They are able to resist extreme vibration with no loss in performance.

High-quality internal threads are wear resistant, Unified and American Standard, class 2B, or ISO Metric standard, class 6H threads. Military versions conform to Unified and American Standard, class 3B.

This threaded insert is a solid metal bushing that is available in stainless steel, steel with zinc plating, or steel with cadmium plating in regular, medium or short length.
