摘要：
A fastening element particularly adapted for use in conjunction with a mandrel for opening the expandable sleeve of the fastening element into secure relationship with a wall having a hole into which the fastening element is inserted. The sleeve is designed to provide a radial channel for enveloping the plate member adjacent the hole. The mandrel becomes a part of the fastener and offers good resistance to shear forces and also provides the means for removing the fastening element as well as fixing it to the object to be fastened.
