Aluminum Profile Accessories for Industrial Framing
Standard and made-to-drawing fastening components for machine frames, guards, conveyors, workstations and modular aluminum structures.
Product overview
Aluminum Profile Accessories for Industrial Framing
Selecting aluminum profile accessories requires more than matching a thread size. The profile series, slot opening, internal cavity, loading method and expected load all affect whether a fastener will install and hold correctly. Longjin supplies slot fasteners for common 20, 30, 40 and 45 series industrial aluminum framing systems.
Our range includes T-slot nuts, slide-in nuts, spring nuts, T-bolts and related connection parts. Standard items support routine frame assembly, while special widths, heights, thread locations and materials can be reviewed from a drawing, sample or profile cross-section. Confirming the interface early helps avoid loose fits, blocked installation and mixed parts on the assembly line.
How to select
How to select
Start with the extrusion rather than the fastener name. Four details usually narrow the selection quickly.
- 01
Profile and slot
Profiles in the same nominal series may use different slot systems. Share the cross-section and slot dimensions.
- 02
Loading method
End-loading parts suit planned assembly; drop-in or post-assembly styles suit frames that are already closed.
- 03
Thread and load
Match the mating bolt and attachment hole, then consider the direction and level of the working load.
- 04
Material and finish
Humidity, cleanliness, appearance and corrosion requirements determine the suitable material and coating.

Manufacturing & quality control
Manufacturing & quality control
Material, forming, threading, finishing and final inspection are controlled against the confirmed drawing or approved sample. Export orders can also follow agreed packaging, labeling and sampling requirements so components are easier to identify at the assembly site.

- Normally 1,000 pieces per specification.
- Custom-part MOQ
- Normally 10,000 pieces, subject to material, geometry and process review.
- Dimensions & tolerances
- Manufactured to the mutually approved drawing. Please identify critical dimensions, tolerances and mating requirements.
- Samples & tooling
- Sampling is supported. Small sample quantities are normally free of sample charge with freight collect; dedicated tooling or die costs are quoted when required.
- Production planning
- Mass production begins after sample approval. Capacity is up to about 5 million standard parts per month and 500,000 custom parts per month; delivery timing is confirmed by order quantity and process.
- Inspection
- Professional inspection equipment is used for dimensional, thread, appearance and fit requirements. 100% inspection can be arranged as agreed for the order.
- Materials & finishes
- Materials can be reviewed to specification; common finishes include nickel plating and zinc plating.
- Material documents
- Upstream material certificates or quality inspection documents can be provided for the applicable order and material batch.
- Packaging
- Customer labels, specification-separated packing and other confirmed packaging requirements are supported.
FAQ
Frequently asked questions
How do I know whether an accessory fits my extrusion?
Send the profile series, slot width and a cross-section drawing or clear dimensions. A name such as “40 series” alone may not identify the internal slot geometry.
Can several nut and bolt types be supplied together?
Yes. A project list can combine standard sizes, with packaging and labels agreed before the order to help your assembly team separate the parts.
Do you support stainless steel and non-standard sizes?
We can review 304 stainless steel and special geometry. Please provide a drawing or sample, the service environment and expected volume for a manufacturing assessment.
