Abstract
A coiled spring wire fastener includes a first end for engaging with the head of a bolt, a midsection of a constant diameter and a second end portion of a conically, tapered shape. In an alternative embodiment, the coiled spring wire fastener includes an annular midsection for engaging a threaded portion of a bolt, a first annular end portion connected to the annular midsection and having a smaller internal diameter than that of the midsection, and a conically tapered second end portion.
