A method of covering a portion of a fastener, protruding from a surface, that comprises providing a cap comprising a wall, a base, an interior, at least partially delimited by the wall and the base, and pawls, located in the interior of the cap. The method further comprises coupling a tooth to the fastener, covering the portion of the fastener with the cap, and positively engaging the pawls with the tooth, such that the pawls are loaded in tension against the tooth.

Method of covering a portion of a fastener protruding from a surface

Ignition-quenching systems comprise an ignition-quenching cover configured to quench an ignition event in a combustible environment triggered by an ignition source associated with a fastener stack. The ignition-quenching cover comprises a porous body that is gas permeable and that has pores sized to quench ignition in the combustible environment. The ignition-quenching cover further comprises a cover attachment feature configured to mate with a fastener attachment feature of the fastener stack. The ignition-quenching cover is configured to cover the fastener stack, which may be associated with a potential ignition source that produces an ignition event in the combustible environment. The porous body may include one or more porous elements that may be formed of various polymeric, mesh, or fabric materials. The ignition-quenching cover may comprise a non-porous frame that is bonded to the porous body and that defines the cover attachment feature.

Ignition-quenching systems, apparatuses, and methods

A system for use in covering a portion of a fastener protruding from a surface is provided. The system includes a cap that includes an interior, a base that at least partially delimits the interior, and pawls on the interior. The system may also include a tooth configured to be associated with the fastener and configured to positively engage the pawls.

Methods for use in covering a portion of a fastener protruding from a surface

A cap for use in covering a portion of a fastener protruding from a surface is provided. The portion includes threads. The cap includes an interior, a base that at least partially delimits the interior, a threaded receptacle on the interior configured to threadably engage the portion of the fastener, and a seal coupled to the base to engage the surface.
