Chem-Set M1-SB50 No-Drill Bonding Fastener

Description

Chem-Set M1-SB50 Fastener combines a male threaded stud with a 50 mm square baseplate that can be bonded to the back of a panel or assembly. The broad plate spreads load into the adhesive layer and creates a threaded attachment point without drilling through the visible face. It is useful for stone, metal, composites, signs, cladding, transportation panels, and fabricated components where surface appearance matters.

Where the Chem-Set M1-SB50 Fastener Fits

The square base provides a large bonding footprint for installations that need more area than a compact stud plate. Once bonded, the projecting thread can accept compatible nuts, brackets, clips, spacers, or other hardware. Designers can place attachment points where the assembly requires them while keeping penetrations and fastener heads off the finished side.

Bonding and Assembly Workflow

• Select the base material, plating, thread size, and thread length for the service environment.
• Confirm that the adhesive is compatible with both the baseplate and the substrate.
• Clean and prepare each bonding surface according to the adhesive instructions.
• Apply a controlled adhesive amount that wets the plate without excessive squeeze-out.
• Position and fixture the fastener so the stud remains aligned during cure.
• Wait for the specified cure before installing hardware or applying service load.

Product Details

• Fastener style: male threaded bonding stud
• Base shape: square
• Base size: 50 mm by 50 mm
• Base thickness: 2.0 mm
• Common inch threads: 10-24, 10-32, 1/4-20, and 3/8-16
• Common inch lengths: 0.250 through 3.000 inches, depending on configuration
• Material and finish options: selected to match application requirements

The completed joint depends on adhesive selection, bond-line thickness, surface preparation, cure conditions, load direction, temperature, moisture, and vibration. Prototype the full assembly and confirm the required safety factor before production. The fastener should remain fixtured until the adhesive has reached the strength required for handling.
