The present invention provides for fastener inserts and methods of manufacturing the same. The fastener inserts include selectively removable tangs which can be broken away more cleanly than with other commercially available fastener inserts. Further, the methods of manufacture offer a significant improvement in the production process.

Cold head stamped fastener inserts including marking indicia

A notch-forming extraction tool for helically coiled wire inserts according to the invention includes a mandrel with a second end having a tooth adapted to form and be received by a notch of the insert. A first end opposite the second end is received in a bushing of a handle portion for connecting the mandrel to the handle. Left-hand rotation of the handle contracts the insert about the second end of the mandrel to facilitate removal of the insert.

Notch-forming extraction tool for helical inserts

Cold head stamped fastener inserts including selectively removable tangs

An extraction and adjustment tool for tangless helically coiled wire inserts according to the invention includes a mandrel with a leading portion having a tooth for reception in a recess of the insert for left-hand rotation of the insert. An end opposite the leading portion is received in a bushing of a handle portion for connecting the mandrel to the handle. Left-hand rotation of the handle contracts the insert about the leading portion of the mandrel to facilitate adjustment or removal of the insert.
