W-Type Fasteners
Material: All parts are
Spring Steel, heat treated,
unless otherwise specified. The only
variations available are those shown with suffix letters in
the part number.
- SS - Stainless Steel
- BE - Beryllium Copper
- P - Phosphor Bronze
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.
