Replacement Morso blade bolt, each blade requires 3 of these bolts to ensure it cannot move whilst cutting.
Common to see these bolts rounded off making replacing the blades an absolute chore, replace as soon as damage is spotted as this will make future blade changes easier and safer.
info: These are not standard 'off the shelf' bolts as such they have to be bespoke manufactured from high grade stainless steel.
