Grass rope nail, also known as wood screw, is a type of screw specifically designed to fasten to wood. It usually has the following characteristics: the thread of the grass rope nail (wood screw) is relatively large, which can be better inserted and fixed in the wood. These threads are usually serrated to increase their grip in the wood. Cone point: The tip of a wood screw is usually pointed to facilitate drilling and entry into the wood. This helps reduce opening resistance and improve fixation. Grass rope nails (wooden screws) are usually passivated to increase their corrosion resistance. This helps prevent screws from rusting and being damaged in humid environments. Wood screws are widely used in woodworking, furniture manufacturing, construction, and other fields that require fastening wood. Choosing the correct size and type of wood screws will ensure good fixation and provide long-lasting connections.

These screws have an oversized "truss" head style with an undercut bottom, low height rounded dome top and recessed phillips drive. The flat bearing surface underneath the head covers a larger diameter than a typical pan head machine screw. This increased surface area reduces the chances of crushing or marring the material the screw is tightened against. Stainless machine screws are commonly used in damp or wet environments for corrosion resistance.
