摘要： A lock spindle blind fastener to be set with a single action tool where the fastener includes a pin or mandrel, a sleeve and a locking collar; the sleeve has an enlarged head which has a straight counterbore for the initial reception and guiding of the locking collar with the counterbore communicating with a bore portion having an entrant resistance angle for reception of the collar during setting. The entrant resistance angle is selected to be of a magnitude to provide hold-off of the locking collar. The strength of the mandrel and other characteristics of fastener components are related to the force required to deform the locking collar along the entrant resistance angle such that a high strength blind fastener is provided which can be set by a single action tool.

摘要： An improved pull-type blind fastener is disclosed comprising a tubular sleeve having a mandrel longitudinally movable within the sleeve for forming a head on one end thereof and a locking collar adapted to be moved into engagement with a lock pocket provided on the mandrel as the fastener is set whereby the mandrel is locked within the sleeve. The locking collar is generally cylindrical in shape having a bore extending therethrough which bore is defined by an inner portion of a first predetermined diameter and an outer portion of a diameter greater than the first predetermined diameter. The enlarged diameter outer portion operates to provide a relieved area at the outer end of the locking collar and immediately adjacent the nose assembly of an installation tool so as to prevent flow or wiping of collar material axially outwardly between the mandrel and the nose assembly of the installation tool during setting of the fastener.

摘要： 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.
摘要翻译：一种由合适的相关金属形成的锁定主轴盲卡扣，其包括心轴，套筒和锁定套环，其中套筒具有具有大于所准备孔的夹角的底部头部的沉头，并且其中套筒头具有用于初始接收锁定套环的直的沉头孔，在设定期间与入口阻力角通信以接收套环。这种入口阻力角小于头下角度。这些角度的关系是允许使用单个动作或非移动头部设置工具。此外，当紧固件已经被固定时，这种角度关系确保了心轴或心轴与套筒之间的有效锁定。
