Wing Nut

Wing Nut
Not sure what nut you have?
Two ways to identify it - whichever is easier with what is in front of you.
1If you have the nut

Find the spanner that fits it snugly, then measure the hole. Our nut identification chart lists every metric and imperial nut we stock side by side, sorted by spanner size.

Open the nut identification chart ›

2If you have its bolt

The fastest check is the male thread: the right nut spins onto its bolt by hand with no force. Identify the bolt size and pitch first with our bolt and screw guide, and the nut follows.

Wing nuts are one of the few nuts that can be tightened or loosened entirely by hand. Two flat 'wings' projecting from the body give finger grip for applications needing frequent disassembly or adjustment — covers, panels, brackets, lighting rigs and hose clamps. We stock 73+ variants across the wing nut range.
