Fastener Nuts That Are Driven By Hand
Designed to be used without tools, thumb nuts are some of the easiest to use fasteners. Available as either knurled nuts or wing nuts, they are made for easy installation and removal, requiring only your hands to tighten or loosen them.
Wing Nuts
Wing Nuts feature two protruding wings on either side of the nut to tighten or loosen by hand. Wing Nuts are commonly seen on assemblies that require adjustment or are not permanent. They are also used when convenience is a driving factor.
Flange Wing Nuts
Flange wing nuts, or washer base wing nuts, are variations of traditional wing nuts. These wing nuts feature an additional integrated smooth washer, effectively combining a flat washer with a wing nut. The flange portion helps to distribute pressure from the fastener assembly over a wider surface area. This allows for an even more straightforward installation and removal by removing the need for a washer.
Knurled Nuts
A knurled thumb nut is a nut with a knurled outside surface, rather than hex. This makes it easy to tighten by hand, as well as adding a decorative finish. Knurled thumb nuts are used mostly on finished products, such as light fixtures, antique cars, and motorcycles.
