Large-Flange Cross-Bulb Rivet Nut 5/16-18 Thread

Large-flange cross-bulb rivet nut with 5/16-18 UNC thread, built with a pre-bulb shank and four cross-slots to expand blind-side footprint for superior pull-out resistance in thin materials. With a wide flange head, steel body, and plated finish, it is ideal for fastening in sheet metal, fiberglass or plastic panels where high grip strength is needed without backing access or in oversized holes.
