Abstract
A method for making a blind fastener that has a flanged outer sleeve and a flanged inner sleeve that are secured together, wherein the outer sleeve has a socket that receives a lug from the inner sleeve to provide joint axial movement and wherein the outer sleeve has a plurality of slits that receive at least one radial projection from the inner sleeve to prevent rotation between sleeves. The inner sleeve has a thinner upper portion and a thicker lower portion with a score line therebetween to facilitate the separation of this portion. The inner sleeve has a central threaded bore to receive a threaded bolt for fastening purposes and to upset the outer sleeve relative to the flanged portion thereof to secure such fastener to a thin workpiece.
