Dart-Type Fasteners

Tinnerman Dart-Type Fasteners are one of a group of Speed Clip Fasteners, which are self-sufficient. These fasteners require no screws, rivets, studs, welds or other secondary fastening devices. These fasteners require only a cavity or mounting hole. These fasteners can be applied from the front or top of a panel thereby eliminating many blind or limited access fastening problems. Being one-piece, these fasteners eliminate excessive small parts handling and parts inventories.

Once applied, live spring tension secures the components between the top and shoulders of the fastener. The amount of clamping action here varies with the material thickness and design of the fastener. When required, most Dart-Type Speed Clip Fasteners can be removed and reused.

How to apply Dart-Type Speed Clip Fasteners
Position Dart-Type fastener in mounting hole of panel or components to be secured.

As the fastener is pushed into the mounting hole, spring arms compress.

As the shoulders clear the panel they expand. This constant attempt to regain its original shape develops live spring tension between the shoulders and the top of the fastener - securing the panels between.
