Chem-Set M1-RB38 3/8-16 x 3 in Bonding Stud

Description

M1-RB38 stud is a Chem-Set male bonding fastener with a 3/8-16 x 3 inch threaded post and a round bonding base for no-drill attachment work. It gives fabricators and installers a threaded mounting point without drilling through the visible face of stone, metal, composite, plastic, or panel assemblies.

M1-RB38 Stud Benefits

• Adhesive-bonded base helps avoid holes, weld marks, and front-face damage on finished parts.
• 3/8-16 x 3 inch male thread gives more reach than short studs when hardware needs extra standoff.
• Round bonding footprint distributes load over the adhesive area instead of placing stress at a drilled edge.
• Useful for fixtures, brackets, panels, and countertop support tasks where hidden attachment matters.
• Shop-friendly format pairs with approved structural adhesives and normal clamp or fixture practices.

Use this fastener when the assembly needs a permanent threaded post but the substrate should not be drilled, tapped, or welded. The M1-RB38 stud is a practical fit for stone fabrication, sign work, marine panels, transportation interiors, composite parts, and general manufacturing fixtures.

Where M1-RB38 Stud Fits

• Bonding a hidden male thread to stone, quartz, or solid surface components.
• Mounting brackets or service panels on composite and fiberglass assemblies.
• Adding a threaded attachment point to painted or finished metal where welding is not wanted.
• Fixture building where the attachment point must sit proud of the surface.
• Repair jobs that need a no-drill fastening point in a constrained location.

Surface Preparation and Use

Clean the bonding area until it is dry and free of dust, oil, wax, polish, loose coating, and release residue. Abrade smooth surfaces when the adhesive system calls for it, then remove sanding dust before bonding. Mark the final position before adhesive is mixed, because a bonded stud is difficult to reposition after cure.

Apply the selected structural adhesive to the base, press the fastener into place, and fixture it so the post stays square while the adhesive reaches handling strength. Do not load the post until the adhesive has reached the cure window required for the substrate, temperature, and service load.
