The shank of this plated steel banjo bolt measures just 0.87" (22mm) long. Note that this is relatively short, designed for low-profile banjo fittings measuring approximately 5/16" thick. (A more common 1/2" thick fitting would only allow about 1/8" of thread engagement, or about 3 threads). Plated mild steel construction is suitable for brake systems. Sold individually. Copper Crush Washers (Part No. 3241-7/16) sold separately.
