Chem-Set's Glue-On Sink Anchor Kit anchors an undermount sink to the underside of a stone, quartz, or solid-surface countertop without drilling through the countertop material. Each set is a threaded stud, a sink clip, a washer, and a wingnut that bond in place with a separate two-part adhesive rather than a mechanical press-in insert. Pick a 1 Set trial pack, the 4 Sets pack for a single sink job, or the 100 Sets bulk pack for a production shop running installs every day.

Choosing the Right Adhesive

Both are sold separately in 25ml syringe, 50ml cartridge, and 400ml cartridge sizes. Shops running several sinks a day usually move to the 400ml cartridge to cut reloads and per-sink cost.
Installing the Glue-On Sink Anchor Kit
- Clean and dry the contact surfaces on both the stone underside and the sink rim
- Position the studs to match the clip spacing needed for the sink's weight and basin size
- Bond the studs in place with Chem-Set 633 Epoxy or 605 Acrylic adhesive, sold separately
- Wait 45 minutes to 1 hour for handling strength before the sink takes its working load
- Attach clips, washers, and wingnuts to draw the sink up snug against the countertop
