Below
are examples of fastener types and their function. Take note of the properties
for each fastener as some are better suited to unique needs.
T-Nuts may be available with a device that positions the T-Nut in the T-Slot,
either temporarily or permanently. Ball springs, spring steel, rubber nubs
and set screws are common with Slide-In or Roll-In T-Nuts. T-Nuts may also
be available in steel with different coatings or stainless steel. |

| Slide-In
T-Nuts Concept |
|
| Slide
In T-Nuts are those that must be loaded in the end of the T-Slotted
profile. Slide In T-Nuts may have further descriptions, such as “economy”
or “standard”, that indicate differences in shape and
/ or relative cost. Preloading is necessary during assembly. |

| |
| Drop-In
T-Nuts Concept |
|
| Drop
In T-Nuts are designed to load straight into the opening of the T-Slot,
then rotate until engagement. The width of a Drop In T-Nut must be
less than the T-Slot opening dimension, thus thread sizes are always
smaller than this opening dimension. |
| |
 |
|
| |
| Roll-In
T-Nuts Concept |
|
Roll
In T-Nuts are unique due to their ability to load in the T-Slot from
the face of the profile. A rolling, or rotating motion is performed
to install these in the T-Slot. Thread sizes less than or equal to
the
T-Slot width are available. These T-Nuts were previously known as
“Drop In”. |

| Self
Aligning T-Nuts Concept |
|
|
|
Self-aligning
T-Nuts have a raised section that extends up into the
T-slot opening. This “neck” is engaged and aligned with
the T-slot
when secured in its tightened position. This feature will center
the threaded hole of the T-nut in the T-slot, prevent rotation and
allow for longer thread dimensions.
Note:
Make certain the “neck” does not extend past the face
of the
T-slot profile, interfering with the connection. |
