Chem-Set M1-RB76 No-Drill Bonding Fastener

Description

The Chem-Set M1-RB76 bonding fastener puts a male-threaded bolt stud on a 76mm round baseplate, so a threaded standoff can be added to a panel without drilling through it. The stud projects from the bonded base, ready to accept a nut, bracket, or mating hardware, which makes it the counterpart to collar-style fasteners like the F2 series.

How the Chem-Set M1-RB76 bonding fastener is installed

The 76mm baseplate is sized for higher-load applications than the smaller bonding fasteners in the line, spreading the mounting load across a larger bonded area. Installers prep the surface, apply a compatible structural or epoxy adhesive, and press the baseplate down until the adhesive sets. The exposed stud is then ready for a nut or matching bracket, the same way a welded or through-bolted stud would be used.

The fastener ships in bags of 50, which keeps per-unit handling low for production runs and repeat maintenance stock. Common thread and length combinations:

Choosing base material for the Chem-Set M1-RB76 bonding fastener

Mild steel base plates cover most indoor and coated-assembly work at the lowest cost, and stainless steel base plates are the right call for wash-down environments, marine exposure, or any assembly that will sit outdoors without a paint or powder coat to protect it. Because the bond, not a mechanical thread, is what holds the fastener to the panel, matching adhesive to substrate is as important as picking the base material.

The M1-RB76 shows up most often on panel assemblies that need a projecting stud rather than a recessed collar: standoffs for mounted equipment, bracket attachment points on thin panels, and field repairs where a stripped or broken stud needs to be replaced without cutting into the panel from behind. Because installation is adhesive-based, it also works on substrates that cannot be welded or drilled, including some composites and coated metals.
