Rivet Nut Inserts

Thin sheet or soft panels and no back-side access? Rivet nut inserts give you strong threads in one shot. Use bubble-back styles when you need higher torque and spin-out resistance. Go split-body metric or fractional to form 4 petals that spread clamp load, helping plastics fiberglass and thin metal hold tight. We keep grip ranges ready for mixed stack-ups.
