ABSTRACT:
A lock spindle blind fastener, formed of a suitable, related metal, which includes a mandrel, a sleeve and a locking collar in which the sleeve has a countersunk head having an under head included angle greater than the included angle of the as-prepared hole and in which the sleeve head has a straight counterbore for the initial reception of the locking collar, communicating with an entrant resistance angle for reception of the collar during setting. Such entrant resistance angle is less than the under head angle. The relationship of these angles is such as to permit the use of a single action, or non-shifting head, setting tool. Also, such angular relationship assures an effective lock between the mandrel, or spindle, and the sleeve when the fastener has been set.
