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
from your Tinnerman Palnut representative or the Tinnerman
Palnut Engineering Department.
U-Type Nut Retainers offer
the same advantages as the J-Type Nut
Retainers. That is, heavy-duty fastening, low fastener
profile, "flot" for hole misalignment, self-retention
and blind location fastening. With the full-sized lower leg,
the U-Type Nut Retainer is preferred
where a full bearing surface between the panels is desired.
They are applied simply and quickly in center, or end-panel
location requiring no special skills or equipment.
How to apply U-Type Nut Retainers
Position the second panel and drive the screw. Both hands
are free to align panels and complete the assembly. Flush
mounting is attained by embossing either panel.
Push into position until extrusion on lower leg snaps into
screw hole. The Speed Nut “floats” in screw-receiving
position to correct for normal misalignment in panel mounting
holes.
Place second panel in position and drive the screw. Access
to opposite side is unnecessary. Flush mounting can be made
by embossing either panel.
U-Type speed Nut can be installed
in center of panel though a rectangular hole, permitting front-mounting
attachments. |

U-Type Fasteners -
Wide Panel
The innovative line of Tinnerman® U-Nut Fasteners
accommodates an unusually wide range of panel thicknesses from
.025" to .150" which satisfies most needs for sheet metal and
plastic assembly. A single Wide Range U-Nut can replace
as many as 5 or 6 separate size nuts required to cover the same
capacity. And, it can be supplied in 8AB thru 14AB
thread sizes.
Engineering, purchasing and manufacturing all benefit from this
unique concept. It provides a greater design flexibility and
volume purchase economy. It reduces the separate number of parts
to buy, stock, handle and inspect. It simplifies applicaiton
and speeds assembly.
The dimensions of the parts listed are envelope dimensions only.
For complete design information, please request a blueprint
from your Tinnerman representative or the Tinnerman Engineering
Department. |
