Quick change fastener

A fastener system for temporarily securing objects, comprising:

• a fastener comprising:
• a housing having:
• a first end face;
• a second end face;
• a shaft extending between the first end face and the second end face;
• a central bore that extends axially at least partially through the housing from the first end face;
• and
• at least one ball lock aperture extending from the bore radially out through the shaft of the housing;
• a first socket extending into the housing adjacent to the first end face, the first socket configured such that rotation of the first socket rotates the fastener;
• a pintle positioned within the bore, the pintle having:
• an actuation end;
• a rod that extends axially through the bore from the actuation end, the rod having:
• a ball transitioning surface;
• and
• a ball locking surface adjacent to the ball transitioning surface;
• wherein:
• the pintle is moveable axially within the bore of the housing such that:
• in a designated lock position, the ball locking surface of the pintle is aligned in register with each ball lock aperture;
• and
• in a designated unlocked position, the ball lock surface of the pintle is moved axially away from each ball lock aperture;
• and
• a locking ball for each ball lock aperture, each locking ball having a diameter larger than the diameter of the associated ball lock aperture;
• and
• a work holder having a fixture hole and a ball lock undercut coaxial with the fixture hole, wherein:
• the diameter of the fixture hole allows the fastener to slide through when the pintle is moved to the designated unlocked position, and the locking ball engages the undercut of the work holder when the pintle is in the locked position.
