Push-on fastener
A push-on fastener for engagement on a cylindrical stud includes a body having oppositely facing first and second exterior surfaces and an outer marginal periphery. A central opening extends axially through the body between the oppositely facing exterior surfaces defining an inner periphery. A first resilient tab includes a first engagement edge and a second resilient tab includes a second engagement edge. The first engagement edge defining an inner periphery of the central opening and the second engagement edge defining a periphery that is outwardly of the inner periphery of the central opening.
1. A push-on fastener for engagement on a stud, the push-on fastener comprising:
a body having oppositely facing first and second exterior surfaces and an outer marginal periphery;
a central opening extending axially through the body between the oppositely facing exterior surfaces and defining an inner periphery;
a first resilient tab including a first engagement edge and a second resilient tab including a second engagement edge, the first engagement edge defining the inner periphery of the central opening and the second engagement edge defining an outer periphery of the central opening that is outwardly of the inner periphery; and
a recess extending between the first resilient tab and the second resilient tab near the outer marginal periphery, wherein the recess extends into the first resilient tab a greater distance than into the second resilient tab.
2. The fastener of claim 1 , further comprising a slot extending axially between the first engagement edge of the first resilient tab and the second engagement edge of the second resilient tab to the recess.
3. The fastener of claim 1 wherein the first tab and the second tab are oriented at an angle from the marginal periphery.
4. The fastener of claim 3 , wherein the outer periphery terminates in a flange extending along an edge of the outer periphery perpendicular to the first exterior surface.
5. The fastener of claim 1 , wherein the fastener is composed of a spring steel.
6. A push-on fastener for engagement on a stud, the push-on fastener comprising:
a body having oppositely facing first and second exterior surfaces and an outer marginal periphery;
a central opening extending axially through the body between the oppositely facing exterior surfaces and defining an inner periphery;
a first tab including a first engagement edge and a second resilient tab including a second engagement edge; and
a recess extending between the first tab and the second tab near the outer marginal periphery, the recess extending into the first tab a greater distance than into the second tab,
wherein the first tab being less resistant to deflection than the second tab causing the first engagement edge to engage the stud at a first location and the second engagement edge to engage the stud at a second location below the first location.
7. The fastener of claim 6 , wherein the recess causes the second tab to be more resistant to deflection than the first tab.
8. The fastener of claim 6 , wherein the first tab and the second tab are oriented at an angle from the marginal periphery.
9. The fastener of claim 8 , further comprising a plurality of first tabs and a plurality of first engagement edges, each first engagement edge associated with a respective one of the plurality of first tabs the plurality of first engagement edges defining an inner peripheral diameter of the central opening that is smaller than the diameter of the stud.
10. The fastener of claim 9 , further comprising a plurality of seconds tabs and a plurality of second engagement edges, each second engagement edge associated with a respective one of the plurality of second tabs the plurality of second engagement edges defining an outer peripheral diameter of the central opening larger than the diameter of the inner peripheral diameter.
11. The fastener of claim 10 , wherein the first plurality of engagement edges engage the stud along the inner peripheral diameter at a first location on the stud and the second engagement edges engage the stud along the outer peripheral diameter at a second location on the stud when the stud is inserted into the central opening.
12. The fastener of claim 11 , wherein the fastener is composed of a spring steel.
