METHOD OF REMOVING A WRENCHING MEANS FROM A BLIND FASTENER

摘要

Disclosed is a method of dressing an installed blind fastener that includes machining through a top surface of the fastener along a longitudinal axis of a core bolt of the fastener and an extension that extends from a body of the fastener until intersecting the undercut between the extension and an upper surface of the fastener to remove the extension.

主权项

1. A method of installing a fastener through an aperture in a work piece having an accessible side and a blind side, wherein the fastener includes a core bolt, a clamp portion and a body that includes an extension that extends from the body, the method comprising:
inserting, from the accessible side, the fastener into the aperture until the clamp portion is located on the blind side; engaging a wrenching surface on the extension with a wrenching means to secure a rotational position of the body; rotating the core bolt with respect to the body to deform the clamp portion to form an enlarged clamp surface against the blind side to seat the fastener in the aperture; and machining through a top surface of the fastener along a longitudinal axis of the core bolt and the extension until intersecting an undercut between the extension and an upper surface of a head of the body thereby separating the extension from the body.
