Chem-Set M1B38 No-Drill Adhesive Bonding Studs – 1/4-20 Thread

Create a strong, threaded mounting point without drilling, welding, or damaging the mounting surface. Chem-Set M1B38 bonding studs feature a 1/4-20 male threaded post attached to a wide 38mm round steel base.

The perforated base allows a compatible structural adhesive to flow through and around the mounting plate, helping distribute the load across a larger bonding area. The fastener can be adhesively bonded to the surface or embedded directly into a molded component during manufacturing.

Choose from four post lengths to match your installation requirements: 3/4 inch, 1 inch, 2 inches, or 3 inches.

Prepare the bonding surface according to the instructions for your selected adhesive. Apply a compatible structural adhesive to the base and position the fastener on the prepared surface. The adhesive should make full contact with the base and flow through its openings.

Allow the adhesive to cure completely before attaching hardware or applying a load. Adhesive selection, surface preparation, cure time, and required fastener quantity will depend on the substrate and application.
