Expansion Nut
Expansion-Type Speed Nut Fasteners provide fast, vibration-resistant
attachments in blind or center- panel locations where only one
side is accessible. They snap easily into square or round holes
and are self retained by spring legs. Special locking tabs are
provided where permanent fastener retention is desired.
As the screw is driven, it expands the spring legs, locking
them over the panel thickness and at the same time providing
a double-locking action on the screw. These easy to apply fasteners
require no special sills or equipment to insall, can be used
in place of weld-, clinch- or stake-type fasteners. Applied
before or after painting, they will not clog - do not require
masking. And, they can be safely applied after procelainizing.
The Dimensions of the parts listed are envelope dimensions
