Hex Nuts
Hex nuts are six-sided nuts that thread onto bolts, screws, and studs to clamp parts together. They're the most common nut style in aerospace and industrial assembly, and they come in a range of heights, materials, and locking styles. This category covers a broad mix: NAS679 lightweight low-height locknuts, finished hex nuts in stainless and alloy steel, and nylon hex nuts for applications that need a non-metallic part.
Learn which materials and finishes are used for hex nuts, and how AN and MS hex nut part numbers are coded. If you need a nut without a locking feature, shop plain hex nuts. To lock a plain nut in place, add one of our jam nuts.
