    • A mechanical fastener assembly is provided for joining two or more workpieces. The assembly includes a mechanical fastener and a slotted insert. The mechanical fastener has a shaft received within aligned bores of the workpieces. The slotted insert surrounds at least a portion of the shaft and has a body portion received within the aligned bores, while an enlarged head portion of the slotted insert is positioned outside of the bores. The mechanical fastener assembly may further include a retaining sleeve when the bores of the workpieces have different diameters. In such case, a midsection of the retaining sleeve is at least partially received within the bore having the smaller diameter, while an enlarged end section of the retaining sleeve is at least partially received within the bore having the greater diameter. The retaining sleeve may be used in combination with or independently of the slotted insert.
    • 提供用于接合两个或更多个工件的机械紧固件组件。 组件包括机械紧固件和开槽插入件。 机械紧固件具有容纳在工件的对准的孔内的轴。 开槽插入件围绕轴的至少一部分并且具有容纳在对准的孔内的主体部分,而开槽插入件的扩大的头部位于孔的外部。 当工件的孔具有不同的直径时,机械紧固件组件还可以包括保持套筒。 在这种情况下,保持套筒的中部至少部分地容纳在具有较小直径的孔内,而保持套筒的扩大的端部部分至少部分地容纳在具有较大直径的孔内。 保持套筒可以与开槽刀片组合使用或独立于开槽刀片。
