Abstract
A barrel nut with features for reducing tensile stresses under heavy load within the barrel nut has a partial-cylindrical body having a first planar end surface and a second planar end surface. A threaded bore extends through the partial-cylindrical body with a central axis substantially parallel to the first planar end surface and the second planar end surface. At least one groove is formed in each of the first planar end surface and the second planar end surface, the groove having a rounded surface extending at least a part of a distance between a curved upper surface of the partial-cylindrical body to a bottom surface thereof in a direction substantially parallel to the central axis of the threaded bore.
Claims19
A barrel nut comprising a one-piece partial-cylindrical body having a first planar end surface and a second planar end surface, a threaded bore extending through the partial-cylindrical body with a central axis substantially parallel to the first planar end surface and the second planar end surface, and at least one groove partially recessed into each of the first planar end surface and the second planar end surface extending at least a part of a length of the partial-cylindrical body in a direction substantially parallel to the central axis of the threaded bore.
A barrel nut comprising a partial-cylindrical body having a first planar end surface and a second planar end surface, a threaded bore extending through the partial-cylindrical body with a central axis substantially parallel to the first planar end surface and the second planar end surface, each of the first planar end surface and the second planar end surface comprising two grooves extending at least a part of a length of the partial-cylindrical body in a direction substantially parallel to the central axis from a curved upper surface to a bottom surface of the partial-cylindrical body.
A barrel nut comprising a partial-cylindrical body having a first planar end surface and a second planar end surface, a threaded bore extending through the partial-cylindrical body with a central axis substantially parallel to the first planar end surface and the second planar end surface, and at least one groove in each of the first planar end surface and the second planar end surface extending at least a part of a length of the partial-cylindrical body in a direction substantially parallel to the central axis of the threaded bore, a bottom surface of the partial-cylindrical body comprising a flange surrounding the threaded bore, the flange being raised above the bottom surface and extending from a circumferential edge of the threaded bore to a side edge of the bottom surface such that a curved upper surface of the partial-cylindrical body at the side edge extends below the bottom surface in a central area.
