The unsung hero holding civilization together one tiny grip at a time.

means A device—like a button, zip, clasp, buckle, or screw—that joins or holds two things securely together.

from From the verb "fasten," which traces back to Old English "fæstnian," meaning to make firm or secure, itself rooted in "fæst" (firm, fixed)—the same ancestor that gives us "fast" in the sense of "held tight" (as in "stuck fast" or "steadfast"), not the speedy sense. The agent suffix "-er" simply names the thing that does the fastening.
