Ball peen bolt

A cable enclosure comprising:

• an end plate releasably secured to a housing to cover an opening defined in the housing such that an interior of the housing is not accessible through the opening, the end plate defining an aperture that extends through the end plate from a first side of the end plate to a second side of the end plate;
• a fastener extending through the aperture, the fastener comprising:
• a head disposed to the first side of the end plate;
• a shaft extending from a first end to a second end, the first end attached to the head, the second end disposed to the second side of the end plate, the shaft having an external thread proximal the second end;
• and
• a nut having an internal thread and an internal diameter, wherein:
• the second end of the shaft has a first condition and a second condition,
• in the first condition, an external diameter of the second end corresponds to the internal diameter of the nut such that the internal thread of the nut mates with the external thread of the shaft to attach the nut to the shaft, and
• in the second condition, the external diameter of the second end is greater than the internal diameter of the nut such that the internal thread of the nut does not mate with the external thread of the shaft and the nut, once attached to the shaft, does not detach from the shaft.

A method of operating a fastener comprising:

• placing a shaft of the fastener through an aperture defined in a member, wherein:
• the aperture extends through the member from a first side of the member to a second side of the member,
• the shaft extends from a first end to a second end,
• the first end of the shaft is disposed to the first side of the member,
• the second end of the shaft is disposed to the second side of the member, and
• the shaft has an external thread proximal the second end;
• attaching a nut of the fastener to the shaft by threading the nut having an internal thread onto the external thread of the shaft;
• and
• after attaching the nut to the shaft, applying a force to the second end of the shaft to enlarge an external diameter of the second end such that the external diameter of the second end is greater than an internal diameter of the nut and the nut does not detach from the shaft.
