Grounding Clinch Stud

Grounding clinch stud: a stud pressed into sheet with a contact face that provides an electrical path to the chassis.

Product overviewOverview

A grounding stud carries a ring of sharp teeth on the underside of its flange. Bonding resistance is the parameter here, not just push-out. Coating on the sheet, oxide on the stud and the contact pressure at the knurl all add resistance, so the joint is measured in milliohms rather than judged visually.

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

Key featuresFeatures

Bonding resistance is the acceptance parameter, not appearance.
Ring teeth pierce coating and oxide to reach bare metal.
Fixing and bonding happen in a single pressing operation.
Tooth height selected for the coating thickness on the panel.

Typical applicationsApplications

Server and telecom rack grounding
Industrial control and distribution cabinets
EV power electronics housings

Selection notesSelection

Specify the resistance limit and the test current; a joint that looks tight can still fail a bonding measurement because of coating between the contact faces.

Frequently asked questionsFAQ

Why does a grounding stud fail a bonding test?

Coating or oxide between the contact faces adds resistance, and the knurl may not have penetrated it. The joint is measured, not inspected visually.

What matters during installation of the Grounding Clinch Stud?

Press it into a prepared hole from one side. Bonding resistance is the acceptance parameter, not appearance.

Manufacturing and inspection

Bonding resistance is sampled with a milliohm meter against the drawing limit.We recommend a pilot assembly at the actual torque and mating part before locking the process parameters for volume.
