✅【M8 Thread Furniture Levelers】Not compatible with 5/16" or metric M6. ⚠️Ensure your existing furniture's threaded hole is 8mm (0.314 inches) for a proper fit. Measure the leveler's outer diameter(avoid ruler for accuracy) and thread count: Refer to the second image for detailed specs before ordering. ✅【M8 Leveler Size】1.46" tall levelers, M8×0.96" thread length, 1" base diameter. Use these to add 0.5" to 0.9" in height to chairs, desks, dressers, patio tables, end tables, customizing the overall height as needed. Recommended for heavy duty furniture with leg diameters over 1-1/4". ✅【No-Slip Rubber Table Feet】Fully rubber-filled construction provides non-slip, scratch-resistant protection for floors.
