1/4" Lock Nut

1/4" Lock Nut (H8) - La Marzocco Group Head

This is an H8 (8 mm tall) 1/4" lock nut, thicker than the standard 5 mm lock nuts, used on the inside of La Marzocco group heads. La Marzocco's own part number for it is L100/5.

• Replaces: La Marzocco L100/5

PRO TIPS

• Don't substitute a standard 5 mm 1/4" lock nut here - the extra height on this H8 nut is intentional for proper thread engagement inside the group head.
