black oxide speaker mounting screws with deluxe 6 prong t-nuts, 1-1/4" (3,175 cm), cross recess, us made
These also work for mounting drivers, handles or anywhere regular wood screws might be apt to pull out. These are not your typical 3 or 4 prong hardware store t-nuts. These have extra sharp teeth and longer shanks to insure that they go in straight and hold tight even in difficult material like particle board. Require 1/4" diameter holes
