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.
Sold as a set of two with four copper washers. 
Designed and Made in the UK by Mike Satur.
