Tap-Lok® Slotted Series - Key Features:
|
Slotted Series threaded inserts are suitable for use in a wide range of machinable softer metals and plastics, particularly those that may contain abrasive fillers.
- Highest pull-out resistance.
- Suitable for a wide range of metals and plastics.
- Superior vibration resistance.
- One-step installation.
Superior pull-out resistance in softer metals and plastics from the external v-form thread.
Cutting slots are designed to quickly tap into the base material and lock the insert in place. They are able to resist extreme vibration without loss of performance.
High-quality internal threads are wear resistant, Unified and American Standard, class 2B, or ISO Metric standard, class 6H threads.
This threaded insert is a solid metal bushing that is available in stainless steel, steel with zinc coating, steel with cadmium plating in coating or brass in regular or short lengths.
