Easy to navigate website & reasonable postage considering delivery from the Netherlands to UK. Found what I needed for my 22 year old GSXR. Would definitely use MSP again

The Screw is a genuine spare part manufactured by Piaggio so you have peace of mind the Screw part being sold by Motorcycle Spare Parts is both original and new.
A flanged head is used where the joint needs wider load distribution without a separate washer, and screw 840542 matches that type of OEM hardware used across multiple Piaggio Group assemblies. It shows up on a broad mix of models and subassemblies, which usually indicates it’s a standardized fastener spec in the Piaggio hardware set.
The flange helps protect softer brackets and plastics from point loading and reduces the chance of fretting at the contact patch. If you’re replacing one due to corrosion or a rounded head, keep the same head form and length to maintain clamp load and clearance.
