M12 x 1.25 vs M12 x 1.0 — Choosing the Right Thread

The M12 banjo bolt family comes in two common fine-thread pitches — 1.25mm and 1.0mm. The M12 x 1.25 is the more common of the two and is found on a wide range of Japanese and European OEM brake components, as well as many aftermarket performance calipers. Always verify the thread pitch of your caliper or master cylinder port before ordering, as the two pitches are not interchangeable. If you require M12 x 1.0, see our SF301-04 listing.

Sold individually. Copper sealing washers recommended — sold separately. Always verify thread pitch and banjo bore diameter of your component before ordering.
