摘要：The insert (10) is provided with at least one annular groove (16) in its outerperiphery and with chamfered ends (14) for entry of the insert into a hole (30) in plasticsparent material (32) with an interference fit so that the plastics material of the hole wall istemporarily displaced and then resiles into the groove (16) to retain the insert in positionin the hole. Opposed shoulders (18, 20) of the groove (16) are sharp edged to shear ordig into the hole wall to also resist axial movement of the insert in the hole (30). Theinsert is primarily intended as an anti-creep spacer to take the compressive load of a boltor like mounting of the component and so avoid or minimise such load on the plasticsmaterial which would otherwise cause creep of the latter and loosening of the mounting.
