Abstract
A unified head for a staked fastener wherein the unified head is made from a first member in combination with a supplemental member, and the two members have at least one shared fiber. In a staking operation that forms the unified head, the operation is conducted in such a manner that a portion of a fiber, initially within the first member or the supplemental member, crosses the boundary therebetween creating the shared fiber, i.e., a segment of a single fiber is embedded in the first member and a segment is embedded in the supplemental member.
Claims3
A method of making a rivet:
- providing a shank having an initial head,
- passing the shank through a body, thereby defining on the shank a gripping portion and a clinching portion,
- placing a supplemental member having at least one fiber therein proximate the clinching portion and the body, and
- staking the clinching portion and the supplemental member creating a unified head.
