Abstract
A controlled dielectric barrier is created surrounding a fastener to isolate its sparking areas. The barrier is formed by creating a cap to define a desired cavity between the cap and the fastener and then dielectric isolation material is placed in the cavity and held in place by the cap until hardened. The cap may then be removed from the fastener as desired.
