ABSTRACT:
A plastics pull-type blind fastener has a pull-part with a pulling stem and legs which pass through holes in a workpiece, shoulders of the legs engaging the workpiece at the blind side, and a push-part with a head to engage the workpiece at the accessible side and a plug extending between the legs to keep them apart after setting. The legs are accommodated in complementary shaped apertures in the head of the push-part, and at least one part has teeth to lock the parts together after setting, and allow removal of the pulling stem.
