- (e) then positioning at least two washers each having an outer diameter greater than the openings in the component but smaller than the openings in the channel walls about a portion of the other end of the pin and welding it thereto so that the pin and washer combinations cannot be removed from the aligned openings and will retain the cap in position on the component.
- 2. The method of claim 1 in which the openings in the opposed walls of the channel of the cap are only slightly larger than the outside diameter of the washer and head of the pin.
