Abstract: A fastener retaining component may comprise a first elongated member. A length of the first elongated member may be greater than a diameter of a fastener receiving element of a component. The fastener retaining component may further comprise a second elongated member. A length of the second elongated member may be greater than the diameter of the fastener receiving element. The fastener retaining component may be configured to be press-fit within the fastener receiving element such that press-fitting the fastener retaining component, within the fastener receiving element, increases a tension in the fastener retaining component to cause the first elongated member and the second elongated member to engage with an inner surface of the fastener receiving element and to retain a fastener within the fastener receiving element.

Abstract: A tool bit is disclosed. The tool bit includes a working portion at a distal end of the tool bit, a threaded portion at a proximal end of the tool bit, a shank extending along a longitudinal axis of the tool bit between the working portion and the threaded portion, and an anti-rotation receiving hole located on the threaded portion. The anti-rotation receiving hole extends through the threaded portion transverse to the longitudinal axis. The threaded portion of the tool bit is configured to engage with threads of a nut, and the anti-rotation receiving hole is configured to receive a pin inserted through the nut.

Abstract: A ground engaging tooth assembly for a cutting edge of a ground engaging implement may include an adapter and a ground engaging tip. The adapter may have a forward extending adapter nose having an inverted or reverse keystone-shaped contour, with the ground engaging tip having a nose cavity for receiving the adapter nose and exterior surfaces having complementary shapes to the adapter nose. The adapter nose and an adapter cavity of the tip may also be configured with complimentary surfaces that increase retention between the adapter nose and the tip when downward forces are applied to the tip. In other embodiments, the surfaces of the tip may include reliefs extending inwardly into the body of the tip to reduce weight and facilitate penetration of the tip into work material as wear material wears away from a front edge of the tip.
