Chem-Set F2-RB23 Round No-Drill Bonding Fastener

Description

The Chem-Set F2-RB23 round bonding fastener is a no-drill threaded collar built for attaching sink clips, brackets, and mounting hardware to solid surface, engineered stone, quartz, and natural stone countertops without drilling through the visible face. It mounts on a 23mm diameter baseplate, 1.2mm thick, and is bonded in place with a two-part structural adhesive to form a permanent anchor point on the underside of the material.

Why Fabricators Choose This Round Bonding Fastener

Countertop and cabinetry shops reach for a round bonding fastener like the F2-RB23 to avoid the chipping risk, dust, and extra labor time that come with mechanical drilling into stone or solid surface. The female threaded collar accepts common machine screw sizes from 10-24 through 3/8-16, so a single part number can cover a wide range of clip and bracket hardware already in a shop’s inventory. Four base plate materials and several plating options let installers match corrosion resistance and budget to the job, from a residential kitchen install to a commercial application with higher moisture exposure.

Thread Options for the F2-RB23 Round Bonding Fastener

Common thread lengths run from 0.250 inches up to 3.000 inches across 10-24, 10-32, 1/4-20, and 3/8-16 thread sizes, giving installers room to match fastener depth to panel thickness or the specific bracket hardware being used. Adhesive bonds the baseplate to the underside of the countertop, then the threaded collar accepts a machine screw from the mounting side, so there is no visible fastener and no need to drill through the finished surface. This is the same no-drill approach used across the broader Chem-Set bonding fastener line for sink clips, brackets, and support hardware.
