Locknuts, often called prevailing torque or locking nuts, are designed for resistance against torque and vibrations. To match our other lamp parts, we offer a line of brass locknuts that includes both regular and heavy hexagon, knurled, and round locknuts that are ranged in size between 3/4” and 9/16”. Though our hexagon and round locknuts are tapped at 1/8” IPS, our knurled locknuts come tapped at 1/4”, 1/8”, or 3/8” IPS. Please note that IPS thread size are not equivalent to Inch Measurements. For complete thread sizing, check out Lamp Parts FAQ section.

In addition to brass products, we can also supply our customers with nickel and steel locknuts, including those that are half-round swivels, hexagons, or zinc-plated and have threads with 1/8”, 1/4”, 3/8”, and 1/2” IPS.
