The 7/16-24 alloy banjo bolt, 24mm long under the head, a step up in thread diameter from the 3/8-24 version and matched to the larger banjo ports found on some calipers, master cylinders and fuel components. As with any banjo bolt it is drilled through the centre and cross-drilled into the eye, so fluid passes through the bolt itself and the banjo fitting can be clocked to whatever angle suits your hose routing before final tightening. Machined from aluminium for light weight and appearance. The larger thread does not mean you can be heavy-handed: alloy threads strip easily, so torque properly and always use a fresh sealing washer above and below the banjo eye.
