 Carr panel
fasteners speed assembly - and hence save money - because they hold
together two or more thicknesses so easily and quickly. They snap in
instantly from one side - much faster than a screw and nut can be
applied.Most
Carr panel fasteners are designed for round holes and expand after
being inserted, thereby maintaining a constant gripping force. Both
permanent and removable types are available in a great variety of
shapes and sizes.
The latest type,
rapidly gaining in popularity, is the ratchet fasteners. Flexible
ribs on the shank bend when the fastener is pressed in a hole, then
snap back inside a hole. These fasteners are "naturals" for variable
take-up applications. |
