ChemSet 740K 50mL Sink Anchor Kit (4 Sets of Hardware + 633 Epoxy)



Backordered - 0-5 day lead time

Chem-Set 740K Sink & Dishwasher Anchor Kit (4 Sets of Hardware + 633 Epoxy Adhesive) contains everything needed for secure dishwasher or sink mounting under natural stone counters without drilling. The kit includes: undermount studs, sink clips, Chem-Set 633 Epoxy (suitable natural stone countertops,) dispensing gun, and mixing nozzles.


  • The anchor kit is ideal for counters made from natural stone (granite, marble, concrete, wood.)
  • No additional glues are needed. The stud base glues to the underside of the counter using epoxy.
  • The 1-1/2″ diameter stud base is designed to fit into tight areas.
  • Easily install sinks using the included wing nuts, lock washers and sink clips.
  • The kit contains a dispensing gun and mixing nozzles good for several applications.
  • Each Undermount Stud set includes four sets of hardware plus dishwasher mounting brackets/fasteners.

Each Kit will Contain:


  1. Remove the cap from 633 Epoxy Adhesive. Dispense a small amount of adhesive until the adhesive is flowing from both chambers of the container.
    • 50ml Cartridge: Place the cartridge into the dispensing gun without attaching the mixing nozzle. Dispense a small amount until both sides dispense at the same time. Attach a mixing nozzle and dispense a 6-8” bead of adhesive on scrap material to purge the cartridge.
  2. Clean the area to be bonded and the glue-on fastener with alcohol. The surface must be clean and dry for good adhesion.
  3. Carefully apply 633 Epoxy to the base of the glue-on fastener and set in desired position on the underside of the countertop around the sink cut-out.
  4. Allow 45 – 60 minutes for adhesive to reach proper handling strength.
    • Note: Adhesive will continue to cure for up to 24 hours.
  5. Once the adhesive has reached handling strength, place the sink into position, mount the ‘Z’-shaped sink mounting bracket onto the glue-on fastener, add the washer, then tighten with the wingnut.
