Tinnerman® U-Type Fasteners
U-Type Speed Nuts perform the same fastening functions as the J-Type, but are used where a full bearing surface on the lower leg is desired. they are self-retained in screw-receiving position to provide simple, rapid attachement of mating panels and cannot turn as the screw is driven.
Corrosion presents no problem, as the Speed Nut will not freeze on screw threads. In fact, the Speed Nut impression actually cleans out rust, dirt or paint clots from the screw threads as they are removed.
The dimensions of the parts listed are envelope dimensions only. For complete design information, please request a blueprint.
