Emhart Fastening Teknologies
The teflon-epoxy coating of the Heli-Coil's Heli-GuardR inserts acts as a neutral barrier between the fastener, inert and the parent material, isolating all three from one another, preventing galvanic corrosion. Additionally, the coating provides added lubricity while installing the inert. The threaded insert eliminates the need for the introduction of such processes as the application of zinc chromate primers.
