HIGH QUALITY: These insert nuts are made from zinc-plated carbon steel, providing strength and good corrosion resistance in various environments. EASY TO USE: These threaded insert nuts are easy to install and versatile for multiple applications. FEATURES: Insert nuts offer advantages over cylindrical nuts and T-nuts because they can be installed from one side of the workpiece. MATCHING KIT: Includes 6 different sizes of nuts (refer to description or images for exact sizes), suitable for a variety of projects. INSTALLATION NOTE: The pre-drilled hole should match the length of the insert nut and accommodate any portion of the bolt that extends beyond the nut into the material. An insert nut creates a threaded socket in wood, similar to a wall anchor. The insert is placed into a pre-drilled hole, where external ribs grip the wood to prevent rotation or pull-out. These insert nuts are constructed from durable zinc-plated carbon steel for enhanced rust resistance. They feature external threads and a hex socket, allowing installation with a hex key. Available in multiple sizes to suit different screw types and project requirements. Note: Measurements are taken manually; please allow a tolerance of 1–3 mm. Color may vary slightly due to lighting and monitor display differences.
