Product overviewOverview

Ground quality depends on tooth penetration and contact pressure. The standoff has to do two jobs at once: hold a thread for the PCB or cover, and carry a low-resistance path into the sheet. Adding height increases the lever arm on the clinch, so the taller the standoff the more the push-out and torque-out matter.

Material: Carbon Steel / Stainless Steel. It is pressed into a prepared hole from one side.

Key featuresFeatures

Added height increases the lever arm on the clinch joint.
Tooth height selected for the coating thickness on the panel.
Stable bonding resistance for equipment with continuity requirements.
Zinc-plated steel or stainless, with conductive finishes available.

Typical applicationsApplications

Industrial control and distribution cabinets
EV power electronics housings
Medical equipment chassis

Selection notesSelection

Check torque-out with the standoff at full height, since a bending load from a cable or cover acts at the top of the column.

Frequently asked questionsFAQ

Does standoff height affect the clinch joint?

Yes. Load applied at the top of a taller standoff produces a larger bending moment at the joint, so torque-out and push-out are checked with the full height in place.

What matters during installation of the Self-Clinching Grounding Standoff?

Press it into a prepared hole from one side. Added height increases the lever arm on the clinch joint.

Manufacturing and inspection

Tooth height and count are checked optically, and face dimpling after pressing is inspected.Alternative materials and finishes can be quoted side by side during sampling, so cost and corrosion resistance can be traded off explicitly.
