Chem-Set M1-RB38ND 1/4-20 x 1 in Bonding Fastener, 38 mm Round Base

Description

M1 bonding fastener gives countertop fabricators and assembly teams a no-drill way to add a 1/4″-20 threaded mounting point on stone, composite, metal, and other finished panels. This Chem-Set stud uses a 38 mm round base and 1 inch male thread length so installers can mount undermount sinks, brackets, clips, and light hardware without cracking the surface or burning coatings.

Key Features and Benefits

• 38 mm round base spreads adhesive across a broad footprint for dependable hold.
• 1/4″-20 male thread fits common wing nuts, brackets, and sink clip hardware.
• No-drill installation helps protect polished stone, engineered quartz, laminate, and coated metal.
• Works well where welding is not practical or where backside access is limited.
• Useful for both one-off field repairs and repeat production mounting work.
• Pairs easily with sink clips, brackets, and other adhesive-mounted hardware systems.

Common Applications for M1 bonding fastener

• Undermount sink anchor points in stone and solid surface tops.
• Attachment points for stamped sink clips and bracket hardware.
• Light fixture, cover panel, and access panel mounting.
• Composite panel assemblies that need a post without through-holes.
• Metal fabrication jobs where heat from welding is not wanted.
• Retrofit work on finished surfaces that cannot be drilled from above.

Compatible Materials

• Granite and natural stone.
• Quartz and engineered stone.
• Solid surface and laminate assemblies.
• Painted or coated metal panels.
• Composite and fiberglass parts.
• Plastic panels where an adhesive bond is preferred.
