Abstract
Abstract A composite fastener for use in attaching a splash guard to a free edge of a flange in a vehicle wheel well and including a sheet metal S-clip, a washer head screw retained against rotation in the clip so that the shank projects from one side of the S-clip and a nut on the outer end of the screw shank. The space between the intermediate leg and the outer leg of the S-clip opposite the screw is adapted to receive the free edge of the flange therein. The screw shank penetrates a portion of the splash guard which is retained by the nut.

Claim 1
Independent Claim
252 words
A composite fastener for use in attaching a splash guard to a free edge of an exposed flange in vehicle wheel well, comprising, in combination: a sheet metal S-clip; a washer head screw; and, a nut for said screw; said sheet metal S-clip having planar generally parallel outer legs and a planar intermediate leg, said intermediate leg having a first slot therein extending inwardly from one end of said intermediate leg toward the opposite end thereof and said first slot having a width to slidably receive the head of said washer head screw without permitting rotation of said screw therein, and the end of said first slot adjacent said one end of said intermediate leg being open and merging into an opening in the adjacent loop connecting said one end of said intermediate leg with the proximal end of a first one of said outer legs, and the second and remaining outer leg having a second slot therein open at one end and extending inwardly from the distal end of said second outer leg, said first and second slots being in overlying registration, the shank of said screw being received in said second slot and projecting from said second outer leg and said S-clip at approximately a right angle thereto, said free edge of said wheel well flange being receivable in the space between said first outer and intermediate legs, said screw shank being passable through said splash guard, and said nut being retaied on the distal end of said screw shank.

A composite fastener for use in attaching a splash guard to a free edge of an exposed flange in vehicle wheel well, comprising, in combination: a sheet metal S-clip; a washer head screw; and, a nut for said screw; said sheet metal S-clip having planar generally parallel outer legs and a planar intermediate leg, said intermediate leg having a first slot therein extending inwardly from one end of said intermediate leg toward the opposite end thereof and said first slot having a width to slidably receive the head of said washer head screw without permitting rotation of said screw therein, and the end of said first slot adjacent said one end of said intermediate leg being open and merging into an opening in the adjacent loop connecting said one end of said intermediate leg with the proximal end of a first one of said outer legs, and the second and remaining outer leg having a second slot therein open at one end and extending inwardly from the distal end of said second outer leg, said first and second slots being in overlying registration, the shank of said screw being received in said second slot and projecting from said second outer leg and said S-clip at approximately a right angle thereto, said free edge of said wheel well flange being receivable in the space between said first outer and intermediate legs, said screw shank being passable through said splash guard, and said nut being retaied on the distal end of said screw shank.
Claim 3
Dependent Claim
32 words
The composite fastener called for in claim 1 wherein said washer head screw has a hex head the opposing parallel sides of which are retained between opposite sides of said first slot.
Claim 4
Dependent Claim
25 words
The composite fastener called for in claim 1 wherein said first and second slots terminate within said intermediate leg and said second outer leg, respectively.
Claim 5
Dependent Claim
