Bonding Studs

Bonding stud with a flanged base and a reservoir groove: adhesive squeezed out on pressing is captured in the groove to keep the bond line even.

Product overviewOverview

Bond strength depends on three things: surface preparation, adhesive thickness and cure. The groove holds the excess adhesive so the bond line cannot collapse below its intended thickness when the stud is pressed down. Without it, pressing force decides the bond-line thickness, and the result varies from part to part on the same line.

Material: Carbon Steel / Stainless Steel. It is bonded with structural adhesive after the surfaces are prepared.

Key featuresFeatures

Reservoir groove keeps bond-line thickness independent of pressing force.
Suits thin sheet, composites and non-weldable substrates.
Bases with a glue reservoir or knurl control bond-line thickness and add mechanical keying.
Epoxy, acrylic or polyurethane adhesives selected to the substrate and duty.

Typical applicationsApplications

Thin-wall housing hardware
Rail interior panels
Curtain wall and decorative panels

Selection notesSelection

For sustained loads, run a creep test; adhesive joints deform slowly under permanent load.

Frequently asked questionsFAQ

What does the groove under the flange do?

It stores the adhesive displaced during pressing, so the bond line stays at its designed thickness instead of being squeezed thinner by higher pressing force.

What matters during installation of the Bonding Studs?

Bond it with structural adhesive after preparing the surfaces. Reservoir groove keeps bond-line thickness independent of pressing force.

Manufacturing and inspection

Bond-line thickness is checked by ultrasonic gauge or cross-section.Alternative materials and finishes can be quoted side by side during sampling, so cost and corrosion resistance can be traded off explicitly.
