    摘要: A locking fastener unit including a spring washer preassembled to a rotary fastener member with mounting means having an axis disposed eccentrically to the axis of the thread convolutions so that retrograde motion of these threaded fastener units is resisted both by the spring tension of the washer and by the requirement that the washer must include a translational movement element as the fastener member is rotated in a retrograde direction.

    摘要: This invention relates to a buckle usable for securing the two ends of a looped band together about a workpiece, the new and unusual feature being directed to the provision of a distortable element provided in the buckle body which as a tension applying tool draws up on the complementary band the distortable element of the buckle gives a visual indication of the appropriate or predetermined tension having been applied to the band. Thereafter, the buckle and band are permanently set relative to each other.
