Chem-Set M1T38 No-Drill Sink Bonding Fastener

Description

M1T38 sink fastener gives fabricators a male threaded bonding stud for undermount sink anchoring without drilling into stone or cutting cabinet structure. The Chem-Set listing describes a 38 mm x 15 mm rectangular base plate with threaded post lengths in the common 3/4 inch and 1 inch range, packaged in bags with wingnuts for shop and field installation work on natural stone, engineered stone, and solid surface tops.

M1T38 sink fastener benefits

• No-drill installation helps protect finished countertops from cracking, chip-out, and layout mistakes.
• Rectangular base spreads load across the bonded area instead of concentrating it at a drilled point.
• Male threaded post format works with common sink hardware, clips, washers, and wingnuts.
• Useful for both production fabrication and replacement anchor work.
• Bag packaging makes it easier to standardize hardware across repeated sink jobs.

This fastener is typically paired with Chem-Set sink clips and washers, then bonded in place with the specified adhesive system. That setup helps installers build a mechanical hold under the bowl while keeping the countertop face untouched, which is especially useful on stone and quartz jobs where drilling is slow, messy, or risky.

Common applications for M1T38 sink fastener

• Undermount sink anchoring on granite, quartz, and solid surface countertops.
• Replacement of failed or undersized sink anchor hardware.
• Shop fabrication programs that want repeatable sink support hardware.
• Field repair work where access below the sink is available but drilling is not desirable.
• Installations using wingnuts and clips for adjustable sink pull-up during cure.
