Helicoil PF Xylane coated Inserts

Helicoil Primer-Free inserts are designed for use in applications where galvanic corrosion between dissimilar metals is a concern. 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.
