Single crown stone fastening rivet nut. Hole diameter Ø12mm, height H=5mm, thread M4, 100pcs.
Stone fastening rivet nut KEEP-NUT® SI-IM1S-M4-H5 is a compact self-anchoring press-in insert designed to create a secure M4 threaded fixing point in stone, porcelain, sintered stone, solid surface materials, HPL, glass, and other solid panels.
This cylindrical single-crown version is ideal when installation space is limited and a clean internal fixing is required.
