Position the threaded connection along the extrusion slot, then lock brackets, sensors, panels and other attachments in place.
Product overview
Slide-In Nuts for Aluminum Extrusions, M3-M10
A slide-in nut moves along the slot of an industrial aluminum extrusion before being locked by the mating bolt. This adjustable positioning is useful for brackets, sensors, guide rails, panels and accessories that must be aligned during assembly. Width, thickness, thread location and the internal slot space all influence the fit.
Longjin manufactures slide-in nuts with common M3-M10 threads. Standard parts can be matched by profile family and slot width. Special cavity shapes, low-profile designs or specified materials can be reviewed from a drawing, sample or extrusion section before sampling and production.
How to select
How to select
The nut should move smoothly during positioning and remain stable after tightening. These details define the correct version.
- 01
Slot opening and cavity
Measure the opening and share a cross-section so the part can enter without excessive movement in the cavity.
- 02
Assembly stage
State whether the nut can load from the profile end or must be added after the frame has already been assembled.
- 03
Thread size
Select the thread from the mating bolt, attachment thickness and purpose of the connection.
- 04
Corrosion conditions
Indoor equipment, humid areas and clean applications may require different materials and surface finishes.
Applications

Manufacturing & quality control
Manufacturing & quality control
Outside dimensions, thread acceptance, sliding fit and surface condition are the principal checks. When a target extrusion is supplied, fit can be reviewed against the section or customer sample before the production batch.

FAQ
Frequently asked questions
Must a slide-in nut load from the end of the profile?
Many slide-in designs do. Other slot-nut styles are available for post-assembly loading. Tell us whether the frame is already closed so the structure can be selected accordingly.
How can movement inside the slot be reduced?
The outside geometry needs a suitable relationship with the cavity, followed by the correct bolt and tightening method. A cross-section or extrusion sample helps confirm the fit.
Can you make a thin design or move the thread position?
Special thicknesses and thread locations can be reviewed from a drawing. A sample approval is recommended before producing unusual geometry in volume.
