MGF and MGTF Stainless Steel Caliper Brake Pipe Banjo Bolts. Fits front and rear calipers and AP red calipers
The stock bolt has a shorter head and it's difficult to get a full purchase with a spanner often leading to the head rounding off or incorrect torque. This new design has a deeper head to avoid this and is machined to closer tolerances using CNC equipment.
The thread length has been shortened to accomodate slightly thinner aftermarket hoses avoiding using double washers.
Always use a M10 x1.0 tap to clean threads before use. A light smear of anti-seize grease to isolate the materials is also adviseable.
Sold as a set of two with four copper washers. 
Exclusive design and Made in the UK by Mike Satur.
Note these are not generic banjos made in China and sold on Ebay these are made specifically to locate the hose correctly and with the correct thread length to accomodate alternative hose unions which are usually thinner than the O.E hoses. These will allow the correct torque without bottoming out in the caliper.
