Heli-Coil Primer Free Coated Inserts
Primer-Free® inserts are designed for use in applications where galvanic corrosion between dissimilar metals is a concern. The proprietary Primer Free® coating not only protects the base material and provides excellent lubricity, but more importantly, eliminates the need for liquid chromate primers. With Primer-Free® coated inserts, the inserts are always evenly coated, providing more accurate bolt torques. When utilizing Primer-Free® inserts, installation time is reduced significantly and total in-place cost is decreased dramatically.
