LOCKING FASTENER

摘要

The present disclosure provides a multiple use threaded fastener having a plurality of redundant locking features. The fastener includes a threaded hollow lock bolt having a tapered internal wall constructed to threadingly engage a threaded aperture in a housing. A threaded lock stud having a tapered external wall is constructed to fit at least partially within the hollow lock bolt and threadingly engage the threaded aperture of the housing and engage the tapered wall of the hollow lock bolt.

主权项

1. A locking fastener comprising:
a hollow lock bolt having a drive head formed proximate a first end and external threads formed proximate a second end thereof, the hollow lock bolt further having a relatively smooth internal wall with an angled taper extending along at least a portion thereof, and a lock stud constructed to engage the hollow lock bolt, the lock stud having a drive head proximate a first end and external threads formed proximate a second end thereof, the lock stud further having a relatively smooth external wall with an angled taper formed along a portion thereof, an angle of the angled taper of the hollow lock bolt and an angle of the angled taper of the lock stud being different from one another, wherein the locking fastener is configured for clamping a first component between at least a portion of the hollow lock bolt and a second component and the lock stud and the hollow lock bolt are configured so that the drive head of the lock stud extends past an interface between the first component and the second component in an installed condition of the locking fastener, and wherein the lock stud includes a solid portion and a circumference of the relatively smooth external wall of the lock stud engages a circumference of the relatively smooth internal wall of the hollow lock bolt to cause the solid portion to block fluid communication through the hollow lock bolt in the installed condition of the locking fastener.
