Application: Fits most sofas, chairs, couches, seats, ottomans, benches, dressers, and end tables available on the market. Full 4-set pack – Everything you need for setup. When you may need furniture leg attachment mounting plates: Attachment points on furniture are damaged or missing the threaded nut; T-nuts have become loose or cannot be installed, causing furniture to become weak or wobbly. These leg attachment plates help repair and strengthen furniture by attaching them over the existing hole in the leg frame, providing a standard 5/16" (metric 8mm) center to accept your furniture legs. Convert furniture from M10 to U.S. standard M8 holes: Some European imported furniture (such as IKEA, Natuzzi, etc.) comes with legs pre-drilled for M10 (10mm) wide bolts. The U.S. standard is 5/16" (known as M8) wide bolt. By using a set of T-plates centered over the existing hole, you can adapt your furniture to accept 5/16" hanger bolts. Note: These are not straight plates – they are 14-degree angled leg mounting plates. Size: 48mm x 48mm What you get: - 4 leg mounting plates - 4 x 5/16" (M8) hanger bolts - 4 x 5/16" (M8) female adapters - 16 x screw adapters for 5mm unthreaded holes
