Metric Banjo Bolt M24X1.50

M24 x 1.5 covers it completely. M24 is the nominal diameter, 24mm, and 1.5 is the thread pitch in millimeters. That's the full metric thread callout you'd match against your port or fitting. The bolt is male on that end, so you're threading it into a female-threaded port. Wrench width is 30mm, total length runs 49mm, and the L2 measurement is 41mm if you need to account for installation depth.
