PREMIUM QUALITY: These insert nuts are made of high-quality galvanized carbon steel material that provides strength and good corrosion resistance in various environments. EASY TO USE: These multi-purpose threaded insert nuts can be easily driven and installed. FEATURES: Insert nuts offer advantages over cylindrical and T-nuts as they can be installed from one side of the workpiece. NOTE: The pre-drilled hole should be as deep as the length of the embedded nut, allowing the bolt to pass through the workpiece via the nut end. Inset nuts provide threaded sockets for wood materials, functioning similarly to wall anchors. These embedded nuts are inserted into a pre-drilled hole, where the outer protrusions grip the surrounding material, preventing rotation or dislodging. Made of durable, rust-resistant galvanized carbon steel. The nut features an external thread and an internal hexagonal hole, enabling installation with a hex wrench. Slotted nuts are preferred over cylindrical and T-shaped nuts due to one-sided installation capability. Available in multiple sizes to accommodate various screw dimensions and project requirements. The pre-drilled hole depth should match the length of the embedded nut to ensure proper fit and function.
