Fastening devices for explosion-proof enclosures

An enclosure comprising:

• an enclosure cover comprising a central portion, a cover flange, and a plurality of first fastening devices disposed along an outer perimeter of the central portion, wherein each first fastening device of the plurality of first fastening devices comprises a first base and a first extension that extends from a first side of the first base at a distal end of the first base, wherein each first extension comprises a first cam surface;
• and
• an enclosure body mechanically coupled to the enclosure cover, wherein the enclosure body comprises at least one side wall, a body flange disposed at a distal end of the at least one side wall, and a plurality of second fastening devices disposed along the body flange, wherein the body flange mechanically abuts against the cover flange, wherein each second fastening device comprises a second base and a second extension that extends from a second side of the second base at a distal end of the second base, wherein the second extension of each second fastening device of the plurality of second fastening devices couples to the first extension of each first fastening device of the plurality of first fastening devices, wherein each second extension comprises a second cam surface, wherein the enclosure cover and the enclosure body are drawn toward each other when the first cam surface of each first extension of the enclosure cover engages the second cam surface of each second extension of the enclosure body,
• wherein the cover flange and the body flange form a flame path that is properly set when the first cam surface and the second cam surface engage each other, wherein the flame path provides an uninterrupted path from within a cavity formed by the enclosure cover and the enclosure body toward an ambient environment outside of the cavity, along which one or more gases from within the cavity cool as the one or more gases travel from within the cavity along the flame path toward the ambient environment outside of the cavity, and
• wherein the enclosure cover and the enclosure body, when coupled to each other using the plurality of first fastening devices and the plurality of second fastening devices, contain an explosion that originates within the cavity.
