Description


Keep-Nut press-in self-anchoring inserts by Specialinsert is a revolutionary press-in self-anchoring insert commonly used for a number of applications including undermount sink installation, ventilated facades, cladding and furniture. These self-anchoring fasteners are designed to install into a wide range of surfaces including Granite, Marble, Quartz, Solid Surface, HPL, Glass, Fiber Cement and other compact materials.

The insert’s small size also lends itself to be installed into extremely thin surfaces while also being extremely strong. The Keep-nut is made with nylon and stainless steel for exterior performance.
