50pcs M4 M5 M6 M8 M10 Zinc Alloy Screw in Type Hex Drive Threaded Insert Nuts Assortment

Description: An insert nut provides a threaded socket for a wooden workpiece, similar to a wall anchor. These insert nuts are inserted into a pre drilled hole by screw in, in that case the external protrusions bite into the wood, preventing the nut from either turning or pulling out. Features: These insert nuts are made from high quantity zinc alloy and comes in a resealable transparent plastic box. Screw in insert nuts have an external thread and hex socket drive and are screwed in with a hex key wrench. Insert nuts are advantageous over barrel nuts and T nuts, because they can be installed from one side of the workpiece. This set of screw in insert nuts come in different sizes and take different screw sizes. The pre drilled hole must be as deep as the length of the insert nut plus any portion of the bolt that may be screwed past the end of the nut in the work piece.
