03 / The processPrepare your drawing
Pressed in.
Ready to build.
The fastener’s clinching feature captures displaced sheet metal, creating a permanent mechanical connection.
Locate the hardware
Position the fastener on the specified side and support the part with the correct anvil.
Apply the press load
Use a controlled squeezing force to form the sheet metal into the fastener’s clinching feature.
Check the installation
Inspect seating, orientation, and hardware count before the next manufacturing step.

Five families.
One finished part.
Combine nuts, studs, and standoffs on the same part. Call out the exact hardware and installation side in your drawing.
01 / Internal threads
PEM nuts
Permanent threads for bolted joints in thin sheet metal. Select the series and shank for your panel.
Check sizes & fit for pem nuts
02 / Flat mating faces
Flush nuts
A low-profile threaded connection for panels that need to stack or sit against another surface.
Check sizes & fit for flush nuts
03 / External threads
Threaded studs
Fixed threaded posts for brackets, covers, and components secured with a mating nut.
Check sizes & fit for threaded studs
04 / Controlled spacing
Through standoffs
Threaded spacers that establish a repeatable gap between panels or mounted components.
Check sizes & fit for through standoffs
05 / Closed-end threads
Blind standoffs
A threaded spacer with a closed end for assemblies that need a clean opposite face.

Match the fastener.
To the sheet.
Fastener series, sheet hardness, and thickness determine whether a clinch will hold. Material and finish also need to suit the assembly’s environment.
- Aluminum sheet
- Select a fastener rated for the alloy, temper, and thickness. Coordinate the installation sequence with any anodizing requirements.
- Steel sheet
- Check the fastener’s sheet-hardness limit, shank length, and specified mounting hole.
- Stainless sheet
- Use a fastener series specifically rated for installation in stainless sheet; ordinary stainless hardware is not automatically suitable.

Call it out.
Make assembly simple.
A clear hardware schedule helps us install the right fastener, in the right location, from the right side.
- 01 / Specify the complete part number
- Include the series, thread, shank code, and length where applicable, plus quantity.
- 02 / Show the installation side
- Mark each hardware location and the side from which it is installed. Allow room for the fastener and mating assembly.
- 03 / Use the specified mounting hole
- Follow the fastener data sheet. Avoid countersinking or deburring the mounting hole unless its installation instructions require it.
- 04 / Leave access for the tooling
- Check edge distance and distance to bends against the selected fastener’s requirements. Include formed views where access is tight.
- 05 / Identify the finish
- Tell us about anodizing, powder coating, and thread masking so the installation sequence can be planned correctly.
- 06 / Confirm sheet compatibility
- Use the specified thickness and hardness range for the fastener. Check stainless-sheet applications against the appropriate series.
