BMP22TN78-1 Button Parts, #22 backs, 7/8" Threaded Nails w/Shells, 1 gross (PER BOX)

This #22 button back has a 7/8" threaded nail. When anchored with a spring lock washer, the threaded nail is a fast, positive alternative to prong tufting. Just insert the nail through the upholstered construction and fasten it on the back with a spring washer. Deep threads are designed so spring washer slides on easy, yet can’t pull off. Nail is rigidly welded to collet. This item is sold in a 1 gross box (144 pcs. of each item).
