W-Types are used in place of Flat-Type Speed Nut Fasteners when it is necessary to turn the nut to tighten. The turned-up wing at each end provides a gripping surface to facilitate turning the fasteners.
The wing can also serve to retain the fasteners in screw-receiving position. Compressed within a channel or saddle bracket, they hold the fasteners firmly in place for blind-location attachments. Spring tension forces assure vibration-proof assembly.
A few of these W-Type Fasteners are modified to permit side application to the bolt. This feature saves assembly time when long threaded members are used. Pressed on the thread at the desired location, two or three turns tightens the fastener in place.
How to apply W-Type Speed Nut Fasteners
W-Types are applied in much the same way as Flat-Types. The nut is held in screw-receiving position with prongs pointing away from the screw as it is started through the impression. Where threaded studs are used, however, the W-Type can be started over the stud, spun to bottom position and locked with a few quick turns using wrench or pliers.
