Hillman Whiz Lock Nuts

Hillman's Whiz Lock Nuts are one-piece, all-metal self-locking nuts that make easy work of securing objects. They simply spin onto matching threads and lock into place with serrated ridges that grip softer materials. Perfect for do-it-yourselfers tackling a variety of projects around the house or garage, the nuts come in various sizes to suit different fastening needs. Simply twist them onto bolts or screws and let the serrations do the work of holding things firmly where you want them. No tools required beyond the nuts themselves.
