A system for fastening a cover to a body of an explosion-proof enclosure using a plurality of fastening devices. Each fastening device can include a first load distributing member disposed on a body flange of a body of the explosion-proof enclosure, and a second load distributing member disposed on a cover flange of a cover of the explosion-proof enclosure. A fastening device can also include a securing member having a top end disposed on the first load distributing member and a bottom end disposed on the second load distributing member. A fastening device can further include a cam rotatably coupled to and positioned atop the first load distributing member.

1. A system for fastening a cover to a body of an explosion-proof enclosure using a plurality of fastening devices, wherein each fastening device of the plurality of fastening devices comprises: a first load distributing member disposed on a first flange of the explosion-proof enclosure;a second load distributing member disposed on a second flange of the explosion-proof enclosure, wherein the first flange abuts the second flange when the cover of the explosion-proof enclosure is coupled to the body of the explosion-proof enclosure;a securing member comprising a top end disposed on the first load distributing member and a bottom end disposed on the second load distributing member, anda cam rotatably coupled to the top end of the securing member and positioned atop the first load distributing member, wherein the cam has a closed position and an open position,wherein the cam, when in the closed position, pushes the top end of the securing member with a first force against a top surface of the first load distributing member and pulls the bottom end of the securing member with a second force against a bottom surface of the second load distributing member,wherein the first load distributing member distributes the first force along its length to result in a first distributed force, wherein the second load distributing member distributes the second force along its length to result in a second distributed force, andwherein the first distributed force is applied by the first load distributing member to the first flange, wherein the second distributed force is applied by the second load distributing member to the second flange, and wherein the first distributed force and the second distributed force are used to fasten the cover to the body of the explosion-proof enclosure and to provide a flame path between the first flange and the second flange of the explosion-proof enclosure. 2. The system of claim 1, wherein the securing member is disposed within a first slot in the second flange and a second slot in the first flange. 3. The system of claim 1, wherein the cam has a closed position and an open position, wherein the closed position secures the body and the cover. 4. The system of claim 1, wherein the securing member and the cam can be removed when the cam is in the open position. 5. The system of claim 1, wherein the cam comprises a feature that is positioned on a side of the cam opposite of where the cam is hingedly coupled to the securing member, wherein the feature is used to rotate the cam. 6. The system of claim 5, further comprising: a tool that mechanically couples to the feature, wherein the tool, when coupled to the feature, moves the cam between the closed position and the open position. 7. The system of claim 5, wherein the feature is accessible proximate to the second load distributing member when the cam is in a closed position. 8. The system of claim 5, wherein the feature is accessible proximate to the first load distributing member when the cam is in an open position. 9. The system of claim 5, wherein the securing member comprises a retaining member disposed on an outer surface of the securing member, wherein the retaining member secures the feature of the cam when the cam is in a closed position. 10. The system of claim 9, wherein the feature comprises a retaining receiver with which the retaining member mechanically couples when the cam is in the closed position. 11. A system for fastening a cover to a body of an explosion-proof enclosure using a plurality of fastening assemblies, wherein each fastening device assembly of the plurality of fastening assemblies comprises: a bracket comprising a top side, a bottom side, and a back side, wherein the top side is movably coupled to a first outside portion of a first flange of the explosion-proof enclosure, wherein the bottom side is movably coupled to a second outside portion of a second flange of the explosion-proof enclosure, wherein the first flange abuts the second flange when the cover is coupled to the body, and wherein the back side has a first aperture;a cam fixture disposed on an outer portion of the back side, wherein the cam fixture comprises a second aperture, a clearance slot, and a cam feature, wherein the second aperture aligns with the first aperture; anda fastening device comprising a proximal end, wherein the proximal end comprises a mating feature that fits within the clearance slot of the cam fixture and is movably disposed within the cam feature between a first position and a second position,wherein when the fastening device is in the first position, the proximal end of the fastening device is disposed in the clearance slot and the cover and the body of the explosion-proof enclosure are not fastened to each other, andwherein when the fastening device is in the second position, the proximal end of the fastening device is disposed at an end of the cam feature, and the cover and the body of the explosion-proof enclosure are fastened to each other and to provide a flame path between the first flange and the second flange of the explosion-proof enclosure. 12. The system of claim 11, wherein the fastening device further comprises a distal end, wherein the distal end comprises quick release threads, and wherein the quick release threads mate with threads disposed in the first flange of the explosion-proof enclosure. 13. The system of claim 11, wherein the bottom side is angled relative to the back side at an angle that is substantially parallel to the second outside portion of the second flange. 14. A system for fastening a cover to a body of an explosion-proof enclosure using a plurality of fastening devices, wherein each fastening device of the plurality of fastening devices comprises: a first load distributing member disposed on a first flange;a second load distributing member disposed on second flange, wherein the first flange abuts the second flange when the cover of the explosion-proof enclosure is coupled to the body of the explosion-proof enclosure;a securing device comprising a bottom end hingedly coupled to the second load distributing member and a top end removably coupled to the first load distributing member; anda cam rotatably coupled to the securing device and comprising varying radii, wherein the cam has a closed position and an open position,wherein the cam, when in the closed position, pushes the top end of the securing device with a first force against a top surface of the first load distributing member and pulls the bottom end of the securing device with a second force against a bottom surface of the second load distributing member,wherein the first load distributing member distributes the first force along its length to result in a first distributed force, wherein the second load distributing member distributes the second force along its length to result in a second distributed force, andwherein the first distributed force is applied by the first load distributing member to the first flange, wherein the second distributed force is applied by the second load distributing member to the second flange, and wherein the first distributed force and the second distributed force are used to fasten the cover to the body of the explosion-proof enclosure and to provide a flame path between the first flange and the second flange of the explosion-proof enclosure. 15. The system of claim 14, further comprising a wear plate removably coupled between the cam and the first load distributing member. 16. The system of claim 15, further comprising a fastener movably coupled to the wear plate. 17. The system of claim 14, further comprising a tool that removably couples to a protrusion of the cam. 18. The system of claim 14, further comprising a locking feature that traverses the securing device and mechanically couples to the securing device.
