HeliCoil Titanium Inserts

•Superior strength-to-weight ratio, ideal for applications where weight reduction is a significant 
   concern
•Excellent low temperature stability. Their low coefficient of thermal expansion and increased 
   material stability makes them suitable for use in satellites and applications where inserts must 
   withstand sub-zero to 600°F temperatures.
•Non-magnetic
•High corrosion resistance

Emhart Technologies HeliCoil Inserts are available in a wide choice of materials & platings to suit specific application needs.

Primer Free (Heli-Guard)

•Designed for use in aluminum and magnesium applications, HeliCoil Primer Free Inserts are 
   manufactured to to meet all relevant Military or Metric Aerospace standards and are coated with a 
   unique resin bonded fluoropolymer coating . This coating forms the barrier between the HeliCoil 
   Primer Free Insert and the parent material, greatly reducing & preventing galvanic corrosion
•Eliminates need for zinc primers
