A fastener shield (100) for use in a fluid flow path within a gas turbine engine for reducing fluid drag and heating generated by fluid flow over a plurality of circumferentially spaced bolts (107). The fastener shield (100) has a radially-extending, downstream-facing mounting flange (104) with a plurality of circumferentially spaced bolt holes positioned to receive respective engine mounting bolts (107) therethrough and to attach the mounting flange (104) to elements of the turbine engine. A curved, upstream-facing fastener shield cover (108) is positioned in spaced-apart relation to the mounting flange (104) for at least partially covering and separating an exposed, upstream-facing portion of the bolts (107) from the fluid flow to thereby reduce drag and consequent heating of the bolts (107). A plurality of closely spaced-apart, spirally-oriented channels (109) are formed in the fastener shield cover (108) for deflecting the fluid flow impinging on the fastener shield cover (108), thereby increasing the tangential velocity and lowering the relative temperature of the fluid flow.
