8 Piece Cast Frame 1-4"-20 Speaker Mounting Kit With T-Nuts

8 Piece Cast Frame 1/4"-20 Speaker Mounting Kit With T-Nuts Get that professional look with these black anodized hex head cap screws. The perfect mounting head for aluminum cast frame speakers 12" and up. Large enough to secure the frame yet small enough to not deform paper and cork gaskets. Kit includes eight 1-1/2" thread length cap screws with 1/4-20 threads and eight self piercing spiked "T" nuts. Minimum cabinet baffle thickness between 3/4" to 1-1/2". Not recommended for speakers under 12" diameter as the heads will be large for the gasket material.
