Description
The SpecialInsert M1 Series are male-threaded adhesive bonding fasteners designed for permanent, high-strength attachment without drilling or welding. Available in multiple base shapes — round, rectangular, and square — the M1 line provides secure mounting points that bond directly to metal, composite, or plastic substrates using structural adhesives.
M1 fasteners are part of our Core Range of stocked solutions, trusted in signage, marine, transportation, and general manufacturing where mechanical fastening isn’t feasible or desired. These heavy-duty studs can also be embedded during molding or bonded post-production for a clean, reliable, weld-free installation.
