A break-away apparatus for electrical and optical connectors (12) includes front and rear fittings (30, 32) with peripheries that have pairs of aligned fastener-receiving holes, and a plurality of fasteners (100) that each lies in a pair of holes and holds the peripheries of the fittings together. Each fastener is a screw with a shank having a threaded front end that engages threads in the hole of the front fitting, and includes a screw head (214) at the rear of the shank which lies against a rearwardly-facing shoulder (172) on the rear fitting, to thereby prevent fitting separation. A bore (142) extends along the axis of the shank, and a rear end portion of the shank has a groove (182), resulting in a break-away portion of the fastener that has a ring-shaped cross-section. The ring-shaped coss-section permits tightening of the screw but results in the screw breaking when a predetermined force is applied to allow separation of the fittings.
