Abstract
This invention provides a sealed fastener that includes a housing and a nut assembly, the housing having a base and a receptacle extending beyond the base on one side, an annular seal being positioned on the opposite side of the base and engaged by a flange of the receptacle which holds the receptacle to the base. The nut assembly includes a threaded member within the receptacle and a sleeve extending through an opening into the base and beyond the opposite side of the base. The sleeve is bendable outwardly to form a flange to cooperate with the base in holding the fastener to a workpiece, the seal including a bead which will engage such a workpiece and prevent leakage when the flange on the sleeve is so formed.
Claims10
A sealed nut device comprising
- a housing having
- a base
- and a closed receptacle extending from said base in one direction,
- said base having an opening therethrough,
- a sealing member extending around said opening and facing outwardly of said base in the opposite direction,
- said receptacle including a shoulder overlying the marginal portion of said base on said one side thereof
- and a flange overlying the marginal portion of said base on the opposite side thereof, said sealing member including a first annular portion intermediate said flange and said opposite side of said base,
- whereby said base is connected to said receptacle and is sealed relative thereto,
- a second annular portion adjacent and radially inwardly of said first annular portion,
- said second annular portion projecting outwardly of said opposite side beyond said flange for engagement with a workpiece,
- and a third annular portion adjacent said second annular portion and extending radially inwardly therefrom to an inner edge adjacent said opening,
- said third annular portion being recessed beneath said second annular portion, said second annular portion being thicker than either of said first annular portion and said third annular portion,
- and nut means, said nut means including
- a threaded portion in said housing,
- and a sleeve extending through said opening and projecting beyond said base in said opposite direction,
- said sleeve being adapted to be extended through an opening in a workpiece and being bendable to form a flange for cooperating with said base to retain said housing and nut means to such a workpiece and to cause said sealing member to engage said workpiece for precluding fluid flow.
