Description
The Chem-Set M1B23 bonding fastener is a heavy-duty male threaded post on a 23mm round baseplate that mounts to a surface with adhesive instead of drilling or welding. It carries a 1/4 inch-20 thread on zinc-plated steel, so it adds a permanent stud to metal, plastic, composite, and other substrates where a drilled hole would weaken the part or break a coating.
Where the M1B23 bonding fastener is used
Crews reach for this fastener when drilling or welding is not an option, such as thin panels, coated metal, fiberglass, and enclosures that must stay sealed. The baseplate spreads load across the bonded area for a long-lasting hold, and bonding rather than welding removes the risk of galvanic corrosion between dissimilar metals. Common work includes mounting brackets, wire-tie bases, standoffs, and access-panel hardware in fabrication, transit, and equipment assembly.
How the M1B23 bonding fastener installs
Clean and abrade the surface, apply a structural adhesive to the baseplate, and set the fastener in place until the adhesive cures. The 23mm round base gives enough bond area for repeated thread engagement once cured. Proven adhesives for these fasteners include LORD 406/19, Chem-Set Ultralok 420GB, LORD 310A/B, and Huntsman two-part epoxies, matched to the substrate. Each pack ships with wingnuts in bags of 50 or 100.
